Hometech pool cover bad quality

Don't ever buy a pool cover from them! It lasts less than a year and will set you back around R4000! After about 18 months the bubbles start popping out of the blanket and renders the blanket semi useless. Homestech, after you complain about this, tells you that you should've done all kinds of things like removing the blanket once a week to neutralise the effects of the pool chemicals, etc. So clearly the product (500 micron) does not meet quality stds! Be warned!
