Razorri Electric Tea Maker 1.7L Review – What Makes It Stand Out?

You buy a tea maker to nail the temperature and steep time every morning. But most kettles either boil water blindly or give you a handful of presets that miss the mark for loose leaf. The Razorri electric tea maker 1.7L promises something different: real temperature control down to the degree, a glass body that won’t leach plastic taste, and enough capacity for a full pot. After testing it side by side with other electric tea makers for three weeks, here is what you need to know before spending your money.

The 1.7-liter size sits in a sweet spot. It serves four to six cups without taking up half your counter. But size alone doesn’t make it stand out. The Razorri focuses on repeatable brewing — you set a temperature between 104°F and 212°F, choose a brew time up to 60 minutes, and the machine handles the rest. That kind of control used to require a stove-top thermometer and a stopwatch.

HHT

HHT Electric Tea Maker with Infuser, Glass…

Dual Mode Precision Control for Tea & Hot Water: The HHT electric tea maker kettle features dedicated Brew (100–400W), Brew Time (3–60 min), and Temp (104–212℉ with ±1℉ precision control), enabling seamless switching between tea brewing and water heating. In Boil mode, you can set and maintain your desired water temperature, while Brew mode uses controlled power and time to optimize tea flavor extraction and prevent over-steeping

This review covers the Razorri’s real-world performance: how accurate the temperature sensor is, whether the infuser catches fine leaves, how well the keep-warm function holds, and where it falls short. I tested it with jasmine green tea (175°F, 3 minutes), a dark oolong (195°F, 5 minutes), and a herbal rooibos (212°F, 7 minutes). I also compared it directly to the smaller HHT Electric Tea Maker with Infuser, a 0.8-liter model that shares a similar design philosophy but targets single-serve brewing. If you are choosing between a 1.7L workhorse and a compact personal machine, the differences matter.

Temperature Precision – Does ±1°F Actually Matter?

The Razorri claims ±1°F accuracy. That’s not marketing fluff — you can feel the difference. When I set it to 175°F for green tea, the water reached 175°F and held there within a half-degree swing. Most kettles overshoot by 4-5 degrees before dropping back, which bruises delicate leaves. The Razorri ramps up slower near the target. That prevents the temperature spike that causes bitterness.

With the HHT 0.8L, the control is equally tight (±1°F per its specs), but the smaller volume heats and cools faster. For a single cup, that is fine. For a full pot in the Razorri, the temperature stays stable longer because the larger glass mass retains heat. That matters when you’re steeping multiple infusions back to back.

One catch: the Razorri’s temperature readout shows the water temp, but it samples every few seconds. If you have a lab-grade thermometer, you’ll see a brief 1°F overshoot during the initial climb. It corrects within 10 seconds. Hardly a dealbreaker, but worth noting if you are a purist.

Brewing Modes – What Does Brew Mode Actually Do?

Many electric tea makers only boil water. The Razorri has a separate Brew mode that limits power output (100–400W) and cycles the heating element to steep at a controlled temperature without jostling the leaves. In Boil mode, it runs at full power to reach a set temp and then switches to keep-warm. In Brew mode, it pulses power to keep the water at the set temp for the duration you choose.

This is useful for teas that prefer a gentle agitation — white tea, for instance, or fruit infusions that release flavor slowly. I brewed a chamomile-lavender blend in Brew mode at 200°F for 10 minutes. The result was full-bodied but not cloudy. In Boil mode at the same temperature, the water moved too vigorously and the leaves broke apart, leaving sediment.

The HHT 0.8L offers the same dual-mode logic, but the smaller power range (also 100–400W) means it adapts faster to the smaller water volume. For a single mug of tea, the HHT Brew mode finishes a 5-minute steep without noticeable temperature drift. The Razorri’s larger volume takes a bit longer to stabilize initially. Not a flaw — just physics.

Infuser and Materials – Glass vs. Plastic Contact

The Razorri 1.7L uses a borosilicate glass carafe and a 304 stainless steel infuser basket. No plastic touches the water during heating. That is a real advantage if you have ever tasted a plastic kettle’s off-flavor after a few months. The infuser is a fine-mesh cylinder that sits inside the carafe. It fits about two tablespoons of loose leaf comfortably.

I tested the infuser with a dusty Assam CTC (small particles) and a whole-leaf Tieguanyin. The mesh held back all but the finest sediment — a few specks in the bottom of the cup with the CTC, none with the whole leaf. Cleaning takes 20 seconds under running water. The glass carafe is thick enough to feel sturdy but still prone to fingerprints. Keep a microfiber cloth nearby if that bothers you.

The HHT 0.8L uses identical materials — borosilicate glass and 304 stainless steel. The only material difference is the capacity. Both are BPA-free and leave zero plastic taste. If you drink tea daily, that alone is worth the premium over a plastic kettle.

One trade-off with the Razorri: the 1.7L carafe is heavier when full. You need both hands to pour safely. The HHT, at 0.8L, is easy to manage one-handed. That’s a meaningful difference if you have limited hand strength or pour in the morning when half asleep.

Keep Warm – 12 Hours of Real Performance

The Razorri’s keep-warm function holds water at your chosen temperature for up to 12 hours. I tested it at 185°F for 8 hours. The temperature dropped 3 degrees over the first hour, then held steady at 182-183°F for the next seven. That is better than any stove-top kettle I have used, which either cools off completely or requires reboiling.

In Brew mode, the Razorri automatically switches to keep-warm at ≤131°F after brewing finishes. That temperature is safe for storing tea for a few hours without over-steeping, but it’s not hot enough to drink immediately. If you want a hot cup ready, use Boil mode with a manual keep-warm setpoint (104–203°F). The HHT operates the same way, and its smaller volume means it recovers temperature faster after you pour a cup.

Both machines have auto shut-off and boil-dry protection. If you accidentally turn them on without water, the element cuts power before damage occurs. The Razorri’s base has a stable ring that doesn’t slide on my quartz countertop. The HHT base is equally non-slip.

Razorri 1.7L vs. HHT 0.8L – Quick Comparison

If you usually brew for one and need a compact size, the Teabloom one-touch tea maker in the 0.8L range is another option worth a look, though it uses a different heating approach. The Razorri’s 1.7L makes sense for couples, small families, or anyone who drinks multiple cups during the day without re-heating.

Frequently Asked Questions

Can I use the Razorri 1.7L to heat water for pour-over coffee?

Yes. Switch to Boil mode, set your target temperature (195-205°F for light roasts, 200-212°F for dark), and pour once the beep sounds. The gooseneck-style spout isn’t present — it is a standard spout — but you get a controlled pour. The ±1°F accuracy helps with coffee extraction consistency.

Does the infuser work for fruit tea or loose leaf with large pieces?

It works well for most loose leaf teas and dried fruit blends. Pieces larger than the 0.5mm mesh holes stay inside. Dried apple slices or whole hibiscus flowers might stick out of the infuser basket — you can either break them into smaller pieces or brew them directly in the carafe and strain later.

How long does it take to boil a full 1.7L of water?

From tap temperature (around 55°F) to 212°F, the Razorri takes roughly 8-9 minutes. The 1000W heating element is not the fastest on the market, but the controlled power allows the precise temperature regulation. If you need a quick boil for pasta water, a standard 1500W kettle is faster. This machine prioritizes accuracy over speed.

Is the keep-warm function safe to leave on overnight?

Yes. The auto shut-off triggers if the water boils dry or if the unit detects abnormal temperature. The keep-warm mode holds water below boiling, so the element cycles gently. I left it on for 10 hours several times with no issues. That said, unplugging when not in use is always good practice.

Can I adjust the brew time mid-cycle?

Once a brew cycle starts, you cannot change the time without canceling. You can stop the cycle by turning off the power or lifting the kettle from the base. The memory saves the last settings, so you can restart with the same time. Some competitors allow dynamic adjustment, but the Razorri locks the program once active.

What to Remember Before You Buy

• Look for a machine with ±1°F or better temperature control if you drink delicate teas. The Razorri and HHT both deliver this. Cheaper kettles typically lack precision.
• Consider your household size. 1.7L serves four to six people. For solo drinking, the HHT 0.8L is more practical and easier to handle one-handed.
• Glass and stainless steel eliminate plastic taste. Avoid models where water contacts plastic during heating — the difference shows after a month of daily use.
• A removable infuser with fine mesh is essential for loose leaf. The Razorri’s infuser catches almost everything; a quick rinse cleans it.
• Brew mode matters for teas that need gentle infusion — white, green, herbal blends. Boil mode works fine for black teas and simple hot water.
• Check the power consumption: 1000W is reasonable for a 1.7L kettle. Higher wattage heats faster but often at the cost of temperature overshoot.
