Didn't know what to expect with this because already mixed reviews etc but for me it's good ,works well (don't know how) but it does. I have shared supply on water and low pressure this overcomes that. The filter bit i wasn't overly bothered for but it definitely makes the water better I would think in a hard water area it would be even better. The 3 settings are great I like rain & jet together, the nozzle is very fine so if you want a huge flow of water this probably isn't for you but it puts plenty out there just in fine spray that's ok for me because it solves my worse problem of no water.
