I am not paid for a review. I bought this kit for my two boys (10 and 6). The product was packaged very nice and came on time. Installation was a breeze. My boys love the colors (red, white and blue). I could not be happier with this product and would recommend for anyone of all ages. One of my Best Buy's on amazon.

Ex Output:
positive

Ex Input:
I got two bottles for my newborn with no issue. On the third bottle, discovered a dropper that wasn't built into the cap. Not sure if it's a defective batch or what. (Which means you'd have to wash the dropper every time... not ideal at all.) I submitted for a return/replacement and the fourth bottle I got had the same issue. If this is just a new design, I'll definitely have to just switch brands. :(

Ex Output:
negative

Ex Input:
Wow. Ordered these as they looked handy and now know just how handy. The assortment of brushes attach in the chuck on any standard drill. I have yet to explore all the things I can clean with these but on what I have, works perfect. Quaility is pretty good and haven't noticed any problems with wear. I guess I could say I'm glad I got these.

Ex Output:
positive
