I bought this seat to replace the Brondell 300 which I used for many years. This is quite the upgrade.  I love how quickly the seat heats up when it "awakes" from eco mode. The spray is far more adjustable and really has a variety of motions as it performs its function.  The deoderizer mode is surprisingly effective.  The dryer mode too is effective and drys in less than a minute. Once you try this seat, you will not want to use a plain old toilet seat. It is easy to install and simple to use.
