Thanks, but I'm still not sold on a solar skimmer of any brand. My pool has two skimmers--one at the north end; one on the east side at sort of the southeast corner. Poolskim could be my third skimmer, on the west side near a place that tends to collect stuff from our normal south wind in the lee of the spa, which protrudes into the pool at the southwest corner. If Poolskim works, it would be an alternative to a solar skimmer, which would be still another electric device operating in the hostile salty chlorine environment of pool water.I know this doesn't answer your question but just wanted to share that my Betta will get stuck at the skimmer entrance when I have my 2-speed on high speed (3450 rpm). When on low speed (1725 rpm) the Betta works fine.
