PROBLEM: After going through 2 sets of these I have thrown them in the garbage. We used all 4 lenses and could not make out what was on them. I can find nothing sharp when looking at my screen. Total waste of money. Bought another brand this weekend to replace these. This is a piece of junk that would be OK if they were 5 bucks. Not recommended. One star for Amazon Prime. As long as you get free shipping, go ahead & try it out. No hassle.

SOLUTION: Bad review

PROBLEM: I was disappointed when this arrived. The sound system is tiny. Not very loud. There are 4 knobs on the front that go from 0 to 9 - and there is no number 10. Don't waste your money - wish I'd spent less for it! My son's room is really small so there's not a lot of noise in there, but he isn't sleeping through it if we turn these on. If you sit close by, it's even louder.

SOLUTION: Bad review

PROBLEM: For years I've had the old LP version which makes playing music quite frustrating because it's so slow - you can't listen over and over. With this CD and the accompanying book, there's no slowness... the pieces vary up and don't just repeat themselves.

SOLUTION:
Good Review
