I have a top of the line of the "most popular" brand bidet and it's very nice and has been reliable over the 6 years we've had it. For our other bathroom, I thought I'd try this Alpha model. Functionally, it is very comparable to our other one that cost three times more. There are a very few functions it doesn't have (that frankly we don't use, like the automatic toilet seat opening...I disable it because it raises the seat every time I enter the bathroom.). The rest of the functions are great...good water pressure, maybe slightly less than the other one, but perfectly adequate.
My only complaint is there is a seam on the toilet seat between the top and bottom of the seat. It is a trap for splashed urine by "those who stand to pee." So have to clean it out with a q-tip...gross. But that's a minor inconvenience.
Otherwise, very good product for the money. I would definitely recommend it.
