Well worth the cost above Tushy and similar bidets considering the many functions and ability to tune them.  Heated seat, warm water storage, fan, retracting sprayer... Just need to make sure you have a socket nearby to plug it into for installation. Nice not to have to run a water line off the sink at all.  Even has a UV light! Only small wish might be that the UV light came on automatically when the seat detects weight. (As it does that anyway)
