I tried the skimmer basket version. It did not fit my skimmer and the 3 adapters were of no help. It was either too big or too small. I couldn't get enough suction without making some MAJOR modifications to it or my skimmer portal. I returned it (at my own $33 expense) within the alloted time frame after going through the RA# number process and was still charged another $10 as a restocking fee because I was returning a "non-defective" unit. So, all-in-all, it const me $43 to TRY to do business with them. That's more than HALF of what I originally paid for them to start with ($71) They did not pay return postage for it not fitting my pool AND they charged me to restock! I hear, now, that many people complain that it doesn't fit their skimmers. There's no way to tell ahead of time that it's going to fit or not. They advertise as if their adapters fix that issue but they do not and should give some EXACT dimensions BEFORE people invest their time and money into this. I just wasted $43 and several hours of my time ordering, trying to do due diligence, trying it out, contacting support, requesting an RA#, driving to the UPS store and mailing it back, searching my emails for my returned money over 2-3 weeks and now, writing this review. My pool is not unusual and is only 4 years old.
