[Q]: Good quality materials and construction. Easy to mount with four bolts on the upper plate then two more in back plate. One of my best purchases ever. Also very stylish, but only time will tell how long it lasts.
[A]: Good Review


[Q]: My son loves these. He only doesn't play with them so they don't last very long but we find that it helps to break them down and put it away a few days before bedtime as the first thing he does is bite on these things :)
[A]: Good Review


[Q]: It made my teeth yellow. I went to the dentist and all of her work shows that the gum inflammation is not caused by bacteria as with this product.
[A]:
Bad review
