Q: My daughter loves her blocks. She will get them all out and look at each one until she finds her favorite. She likes to shake them and see what each one does. These are cute little blocks that have hours of imaginative playtime inside. They also have blunt corners, so no sharp edges like wood blocks for the safety of smaller children. The fact that they have the letters of the alphabet and a corresponding object inside makes them a great learning tool even for older tots. We have really enjoyed these and recommend them to our friends.

A: Positive

Q: The bed needs air refilling more often than I thought it would- every 3 days at the most. So much so that if I didn't pump it, the bed would all be like a water bed with "jelly-like" feeling. To lessen this effect I situated it in a corner of the room against the walls. Further more, what surprised me was the round water condensation on the bed sheet just underneath my (head) pillow in the morning. But what confuses me is that in the evening the bed feels cold (or the air inside feels cold).What I like about it though is that the pump works real fast in inflating- although it is loud for an evening activity.

A: Negative

Q: My size medium was true to size. This made my waist smaller and while I had it on, I didn't eat as much because of the pressure, it makes me feel full; however, all of the cinchers do this as it is its purpose. I did like the fact that it's shorter from the lower back and a bit longer on the tummy... BUTTT... a HUGE BUT for me... What I didn't like was that it made big bulges of fat on my upper back (eewww!)... and I don't even have back fat!!! So to me this defeats the whole purpose! All it did was cover my stomach fat but GAVE me back fat!!! Also, what's going on with the price increase?? I just bought this 3 weeks ago for $30, now it's $45!
