Question: Does this item works under 220V?
Document: Works great! Best item bought for that room in a long time. Makes coldest nights feel even better than before.
I bought this item for my 89 year old aunt. She absolutely loves it. The warmth and comfort of the toilet seat is very appealing to her.
works great, comes in handy for those comodes near an exterior wall in the winter months. Unplug it in the summertime...
It works fine, thanks. It definitely met our expectations. I do not know why you need so many extra words in your guidelines.
Funny thing is their website says they strive to perfection and want to make their customers happy, what a load of crap, so enjoy it while it works, just hope you never need customer service or a replacement, because you wont get it!
This is a great product that works exactly as advertized. My girlfriend is very, very happy with this gift. This is also a great company with excellent customer support and service! I would recommend this to anyone and everyone interested in  making the ladies in your life very happy!
You don't really notice the heat - which to me is good. What you do notice is the lack of cold! My wife has given me a hug and kiss after each use so far ... it's the hit of this Christmas season in her book. I highly recommend this - it works great, is nicely designed, attractive and reasonably priced.
I don't know why I waited so long to purchase this, other than trying to convince my wife that this would make a big difference to our "daily" routine. It took her all of two days of "oooh, aaah, hey - this feels really good!" before she admitted that for once, my shopping prowess had paid off.The heated seat works exactly as advertised.
I bought one of these over 2 years ago for my wife for her birthday, I believe I bought it on Ebay(NEW!) at the time. The seat works great, we don't abuse it and leave wiring slack, so not to break it. Tonight at Easter dinner my wife told her mother she's going to get one for her, so hubby went on Amazon to check prices!
We let the room get pretty cool at night, and my partner needs a bedside commode. It was a little tricky attaching this heated toilet seat to a portable commode, since the seat is designed to fit onto a regular toilet. However, a friend figured it out and it's turned out to be a great comfort. It certainly works well, is safe, and is an excellent buy compared with competing models.
