I haven't used one of their skimmers, but thier heaters and air pumps are top notch. I've sold lots of the Pro Heat and Pro Heat II heaters with never the first unhappy customer. I use them in all the customers tanks that I maintain. I would highly recommend the Pro Heat II...its digital readout is very convenient. I've also used a couple of their air pumps and found them to be powerful, VERY quiet, and long lasting.
