When used in conjunction with a new water filter i no longer have to replace my Brita when we change filters. Very easy and fast to get the water flowing. You can switch them out more then once.
Good Review

I purchased this little converter for my Samsung 3D TV. It works great. The best part is that unlike other converters in it's price range - I can now receive all of the TV channels without having to hook up an extra antenna which was costing me $80/month before.
Good Review

this tv worked great for 6 months and then all of a sudden started shutting off by itself which made me very mad.
