Review on 6-Pack of Bulbmaster 40W Microwave Appliance Replacement Light Bulbs for GE Ovens, Replaces Part WB36X10003, E17 Base, Length 2.5 Inches by Tom Roberts

Another Chinese garbage. I was specifically looking for a four pin bulb. The product image shows a four post filament mount. What I received is a bipolar lightbulb. I didn't get what I was supposed to get. The description says one thing, the reality is quite different. Very typical of what you'll find at Revain these days. A thread structure with four columns is more reliable than one with two. That's how much vibration a microwave fan causes.
