The Heller HMW25B is a 25-litre digital microwave rated at 900W, with ten power levels, defrost and a 270mm turntable. Those published specifications describe its size and features, but the public CHOICE listing does not reveal its cooking-test results. CHOICE also labels the model discontinued, so check current stock rather than assuming it is still sold new.
What the Heller HMW25B specifications tell you
GAF Control’s product sheet lists the HMW25B as a 25L microwave with 900W output. It is a basic countertop microwave rather than a model whose specification sheet establishes advanced cooking functions: the listed features are defrost, ten power levels, an LED display and clock, a cooking-end signal, and a child safety lock. The sheet does not state that it has a grill or convection mode.

Does the review evidence show how well it cooks?
CHOICE has a review listing for the HMW25B, but its public page does not expose the Expert Rating or cooking-performance, reheating, defrost, reliability or satisfaction scores. Those results are members-only, so they cannot be used here to claim that the microwave performs well or poorly in comparison with other models.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
CHOICE’s publicly visible specifications show 900W, ten power levels, external dimensions rounded to 28 × 48 × 42cm, and a 27cm turntable. These rounded dimensions and turntable size broadly align with the manufacturer’s more precise figures. The listing is useful for confirming model details and discontinued status, but its public information is not a substitute for accessible test results: CHOICE’s Heller HMW25B listing.
Will it fit your kitchen and cookware?
The manufacturer gives overall dimensions of 278.2mm high, 482.8mm wide and 423.7mm deep. Allow extra space if your intended position needs ventilation or clearance; the cited specification sheet provides the appliance dimensions, not a recommended installation clearance. The 25L capacity is the stated cavity volume, not a guarantee that every dish of a given external size will fit.

Inside, the cavity is listed as 212mm high, 340mm wide and 363mm deep, with a 270mm glass turntable. Check a dish against the cavity and turntable measurements, and leave room for the dish to rotate. These dimensions are more useful for a fit check than capacity alone.
Is the Heller HMW25B still available?
CHOICE marks the model discontinued. That indicates it is no longer a current model in that listing; it does not prove that every retailer has stopped selling remaining stock or that second-hand units cannot be found. No live stock or current price is established by the cited sources, so confirm that a seller has the exact HMW25B before purchasing.

If considering a used or clearance unit, verify its condition, included turntable and warranty terms with the seller. The manufacturer sheet documents a 270mm glass turntable, but the sources here do not identify a compatible replacement-part number. Do not assume a generic 270mm tray will fit or work correctly.
