This looks inexpensive, but does that mean it's cheap?

I looked at similar items and most had poor reviews...IMHO, if you are on a budget, best bang for your buck is an intex SWG...similar to this one

If you do a search on ChlorEase you will see it has come up several times. The most through discussion was here. The overall impression I got was that it worked, but most people who tried one ended up switching to something else after a while.
