4.5 stars The vented bottles helped so much with my baby’s gas problems. Took half star off cuz they are diff prices depending on color, wished they were same prices

positive

Not water tight...? moisture inside lenses after only a couple weeks of installed use. Was sent replacement, and it did the same after only a couple weeks. Then after about 4 months half of the lights stopped working.

Ex Output:
negative


Ex Input:
Doesn’t work at all. Tried 20 different games, tried to clean, for an hour tried turning on and off. Dead on arrival. You would think someone would at least test these before selling, shipping, and then dealing with returns.

Ex Output:

negative
