Query: False design and/or material

There's no doubt that it's a great frother! It does what it's supposed to do; it froths any kind of milk darn good!Sharing my 3-week-experience, lactose free milk worked the best. The foam stayed longer than other milk. The fresher the milk is, the more foam you get as well.I would have loved it more if it did not have design and/or material problem.It's made out of cheap plastic. The body can't get a hold of its own lid to battery. I wasn't comfortable using it because it's just about to pop out of the handle while frothing.I tried to tighten the screws in, but it didn't do much.Finally Amazon sent me a replacement, however it came with the same problem.I am afraid I should return both of them and get a stainless steel version.
