Product review (4 stars): attaches firmly
It fits well and works well, so far after a week. Do not buy non-original lamps. They do not fit well. Since microwave fan causes vibration, non-original lamps become loose. If you are lucky, you may find something that fits tightly. If you are like me; do not waste time and buy the original part. You know it's going to attach firmly. I am giving 4 stars because I think it is too expensive for single lamp.
