The Quick Verdict (Skip to Your Situation)
Not here to read the whole thing? Here's the decision matrix:
| Use case | Best pick |
|---|---|
| Single person / office, 1-2 cups/day | **Stainless Steel 1L** – lighter, cheaper, more durable |
| Family, 3+ people, heavy tea/coffee drinker | **Glass 1.7L** – bigger, prettier, watch the boil |
| Sensitive to plastic taste or odor | Glass > Stainless |
| Frequently moved / rental kitchen | Stainless – won't shatter if knocked |

Price First: Closer Than You Think, But Not Identical
From current Amazon search results:
- **Amazon Basics Glass Carafe 1.7L**: ~$22 (CNY 153.94–159.46)
- **Amazon Basics Stainless Steel 1L**: ~$15–$22 (CNY 106.08–153.94)
The stainless steel variant is frequently 15–30% cheaper at any given moment. Not a game-changing difference, but when you're using this appliance multiple times daily for years, spending a bit more on the one matters more than the price tag itself.

| Auto shut-off | ✅ | ✅ |
| Boil-dry protection | ✅ | ✅ |

When the Glass 1.7L Makes Sense
The upsides
Visual feedback is real: The single biggest differentiator is seeing the water boil. If you've ever felt satisfaction watching a microwave turn, you'll understand. For tea drinkers watching leaves unfurl, glass offers something steel cannot.
Better for families or heavy users: 1.7L means you can fill it once and serve multiple people. One verified purchaser with a family of 6 said she uses it for pasta water, vegetables, oatmeal, ramen – multiple times daily, and it's still going strong after a year of daily use. You can't do that with a 1L kettle.
Looks better on the counter: Multiple reviewers specifically call out that it "looks expensive" and "looks nice on the kitchen counter." Blue LED + glass = a small appliance that doesn't look like a budget buy.
The downsides
Glass breaks (eventually): A consistent complaint pattern: the glass carafe can crack unexpectedly. One user reported it "developed a crack out of nowhere" after two months. Another had the auto shut-off fail and kept boiling until the water fully evaporated. The majority are fine – but glass has an inherent fragility steel doesn't.
Heavier to lift: A senior reviewer (right-hand injury, weaker left arm) specifically chose the smaller 1.1L glass model over the 1.8L because "it's light." But compared to the stainless steel, glass at equivalent capacity is noticeably heavier – important if you have mobility concerns or just don't want to strain when pouring.
Hot to touch when boiling: Several reviewers note the glass exterior gets scalding hot. The plastic handle strip helps, but brushing against the glass body when it's just boiled is genuinely painful.

When the Stainless Steel 1L Makes Sense
The upsides
Durability is a feature: Drop it, knock it, store it in a chaotic cabinet – stainless steel forgives. For rental kitchens, households with kids, or anyone who treats their kettle rough, this matters more than any spec sheet can quantify.
Better heat retention: Stainless steel double-wall construction holds heat longer than single-layer glass. If you often boil water then forget about it for 10 minutes, the stainless version will still be noticeably warmer when you finally pour.
Right-sized for one person: Here's an underappreciated truth: 1L for a single person is actually *more* appropriate, not less. Boiling 1.7L when you only want one cup means either drinking lukewarm water as it sits, or re-heating – both worse experiences than just boiling exactly what you need.
Less expensive: 15–20% cheaper at current pricing. For a daily-use appliance, the savings compound across years.
The downsides
You can't see the water: The #1 complaint across 44,671 reviews is not being able to tell how much water is inside. People accidentally run it dry, overestimate how much is left, or just feel anxious about not having visual feedback. Even with boil-dry protection, knowing is better than hoping.
Less visually appealing: Functional buyers won't care, but if your counter aesthetic matters to you, stainless steel reads as "utilitarian" rather than "kitchen upgrade." The glass version wins on looks every time.

What Real Reviewers Actually Report
Diving into the review patterns at scale:
Glass 5-star highlights: Fast heating (1.5K+ mentions), attractive design (637 mentions), easy to descale with lemon juice, BPA-free peace of mind, auto shut-off satisfying "click"
Glass complaint themes: Durability concerns (533 mentions), glass cracking unexpectedly, rare auto shut-off failures, spout size and pouring angle issues requiring significant tilting
Stainless 5-star highlights: Reliable (1.2K mentions), great value for money (613 mentions), lightweight (505 mentions), accurate auto shut-off, holds up well after months of daily use
Stainless complaint themes: Spout angle issues (small spout + narrow top means tipping far forward to pour), some units failing within ~a year, no visual feedback on water level
One pattern worth flagging: several long-term reviewers (1–2+ years) on both models report their units still working perfectly. This suggests both are reliable when they work, but neither is guaranteed – glass has a higher durability ceiling but a lower floor due to breakage risk.

The Actual Decision Framework
Choose the Glass 1.7L if:
- Your household has 3+ people, or you boil 4+ cups daily
- Visual aesthetics and watching the water boil matter to you
- You mainly drink teas where observing the steep matters (green, herbal)
- Your counter is stable and you don't move the kettle often
Choose the Stainless Steel 1L if:
- You're buying for yourself or one other person, 1–2 cups daily
- Durability and drop-resistance matter (kids, pets, tight storage)
- You want to spend the least for a fundamentally equivalent experience
- You prioritize function over form
