Skip if
Skip it if you want a gooseneck spout for precise pouring, this is a standard kettle. Also skip it if you need maximum capacity with the fastest possible boil; 1100 W is less powerful than the 1500 W kettles common in the category.

Overview
At $27.99, the Chefman RJ11-17-CTI-RL punches above its price class by including temperature control in a borosilicate glass body. Borosilicate glass is more durable than standard glass and more resistant to thermal shock, which is a meaningful material upgrade over the plastic-bodied kettles that dominate this price tier.
The 1.8 L capacity is on the larger side for a household kettle, accommodating several mugs per fill. The stainless steel accents pair with the glass body for a finish that reads as more premium than the price tag suggests. At 1.2 lb, the kettle is remarkably light for its capacity, useful for frequent lifting and pouring.
With 16,700 ratings at 4.4 stars and 5 purchases in the past month, the demand signal is solid if not explosive. The 1100 W rating is the main limiting spec, it will boil a full 1.8 L more slowly than a 1500 W unit. But for the buyer who wants temperature flexibility and a glass body under $30, the tradeoff is easy to accept.
Pros
Borosilicate glass body, more durable and heat-resistant than standard glass
Temperature control for delicate teas and different brew methods
Light at 1.2 lb despite 1.8 L capacity
4.4 stars from 16,700 ratings, well-validated at this price
Priced at $27.99, notably affordable for a temp-control glass kettle
Cons
1100 W is slower than 1500 W alternatives
Standard spout, not a gooseneck for precise pour control
Glass requires more careful handling than stainless steel
Performance notes
1100 W heating element in a 1.8 L borosilicate glass body with stainless steel accents. Operates at 120 V. Weight is 1.2 lb at dimensions of 10 x 5.5 x 4 inches. Temperature control is listed as a feature per the model name designation.
What buyers say
16,700 ratings at 4.4 stars is a large, trustworthy sample. Buyers at this price tend to be surprised by the glass build quality and temperature options. The slower boil at 1100 W is the most common gripe, but most reviewers accept it as a reasonable tradeoff for the price.
What temperatures can the Chefman RJ11-17-CTI-RL be set to?
The model is described as a temperature-control kettle. Specific preset temperatures are not listed in the published specs, check the product listing for the exact preset options, as these can vary by version.
Why borosilicate glass instead of regular glass?
Borosilicate glass handles rapid temperature changes better than standard glass, reducing the risk of cracking when you pour in cold water or heat it repeatedly. It is the same material used in laboratory glassware.
Is 1.8 L a good size for a small household?
Yes. At roughly 6 to 7 cups per fill, a 1.8 L kettle is comfortable for two people and works for one person who dislikes refilling frequently.
