It was relatively easy to install, we were able to do it with only a few hiccups (needing to tighten the water connections after the first go), and we are completely un-handy people. For now we have it connected to power via an extension cord, but you should have an electrician do the wiring in the wall if you don't have a plug close enough to the toilet.
When we bought it last month, the price was considerably less on decorprice than elsewhere. Maybe we got it on sale? Because now it is more in line with what others are selling it for.
Once you get used to using it, you will want one on every toilet in your house. For now, the powder room is getting more use than the other toilets!
