I gotta say, I went into purchasing this item cautiously optimistic at how it would perform. I mean, it was 20% the price of the similarly designed Delta (GR250) Glass Rinser. (There is a cheaper GR150 but that is plastic versus full metal construction).Installation was not hard at all, I tee'd off of my hot water line to get a nicer clean on my glasses and the included tee worked like a charm. I didn't have to drill a hole in my countertop because I installed this rinser in place of my dishwasher air gap (Replaced it with a high loop to meet UPC requirements) The hardest part of this install was the re-routing of the dishwasher line , getting it to mate up properly to my GD and then finding out that my garbage disposal has a small leak, but that's a story for a different review.So far, this has been making washing water bottles, cups, coffee mugs a CINCH! SO much so that i'm starting to do dishes on my own instead of waiting for the wife.. That alone should make the purchase worthwhile (in her eyes). The only downside I've seen thus far is that after use, there is a small puddle of water that pools right at the lip of the rinser; a small price to pay for a MAJOR time saver. This was worth every penny. Highly recommend it!
