This item is an excellent replacement. Quality is great...they are not giving these away...but after getting 12 years from my original S8M500 its what to be expected. I had a medical issue, so I could not rinse my filter, and I believe my pool pressure got extremely high, thus fracturing my OEM top housing. Polytec got this to me in "record" time...I am still pleasantly shocked on how "fast" I received this item.
