It works great. I use one on my EC65. Last year during first start up the filter clogged up a bit with DE. I used the wand for 5 mins or so allowing the DE and crap to fall out the waste hole and worked perfect for the entire season. I think I might have backwashed once after that last season.
I just used it again last night to give the inside a good cleaning. Pressure is now holding steady and the pool is crystal clear. It helped me solve the low pressure at the return jet problem I was having the other day.
