Bests & Worsts Reviews from Amazon

I had to change my review here. I bought this product in May and it already is a lemon which is a polite way to put it. It worked well enough for about six weeks but now refuses to open bottles. I say this meaning when you press the down button (which pulls out the cork) nothing happens. No sound, no motion, no nothing. I have this thing fully charged too. I contacted the seller and requested a replacement and have heard radio silence from them.
