Query: Ordered, didnt work, sent back, received replacement, didnt work, sent back!!!

I thought this microwave was a bargain. When I received the first one, I set it on the counter and realized that it wobbled. Apparently, due to poor manufacturing, the base of this microwave was uneven. I contacted Amazon and they promptly sent out a replacement. Before its arrival though, I thought I could use the wobbly microwave. Thats when I discovered that it continually lost power (I checked it on several outlets). The side of the oven also would get very hot. I boxed it up and returned it. Today I received the replacement and (surprise! surprise!) it wobbled also. I tested it in different locations just to be sure it wasnt the counter. Im sending this one back also. I contacted Haier and they said such problems are unusual. I'll give it one more chance. Third time's a charm, I hope.
