I have been very tempted to try it out but when I went to the walmart to pick it up, it seemed awfully expensive and I figured I'd hold off til there were more reviews of it. I did get that Mr Clean car cleaner thing though and that turned out to be worth the money so who knows - I'll prolly get the shower thingie too.
LOL, yes, I'm a sucker! LOL I actually got it w/a $5.00 off coupon at Target so it wasn't too bad. I have been using it for about 21 days now and did not start with a totally clean shower. It was a grimey mess either though. It definately helped. It's not a miracle worker so there are spots I still need to clean by hand but if you are not into scrubbing the entire shower/tub by hand all of the time then I'd say it's worth it. The only thing that is a pain in the arse for me is that my shower does not have any shelves for shampoo and stuff in it so we have the thing that hangs over the shower head to store that stuff. Well, that's where the shower clean thing goes so I have to switch them around every day unless I want to put something up on the other end to hang the cleaner from which I really don't want to have to do...
Also, I think it will be an expensive thing to use all of the time so I am probably going to use the hand held daily shower cleaners in between. They help to MAINTAIN an already clean shower and are much cheaper. When I need to CLEAN again I will use the automatic one.
