Not bad.  The instructions were thorough, and the decals looked good once mounted.

This worked well. Had a few problems with bubbles  but they work their way out. Was pretty easy to put on and had good instructions. I received this discounted for review.

The instructions were good, still a little rough to line every thing UP. But it's worked well.

Excellent. It works as advertised,(expected) and had clear, easy to follow directions. (Pleasant surprise/bonus) So many times these gadgets have incomprehensible directions.

Good product.  Worked well.  We heard heartbeats when baby was near surface and more toward end of pregnancy.  Need a quiet place to listen, as the baby heartbeats are fast and fainter than expected with all the water and such to go through:).  It takes a bit of practice and I didn't hear much for a while.  Would give it 5 stars if the ear pieces weren't so hard and tight in the ears.  Ouch. But, manageable.

Impressed with the directions. My 7 year old navigated the set pretty well without only a little guidance from me.

at first we didn't soak it long enough, but after adding water it worked.  Directions on how to use would have been nice
