Actually, I'm glad to see that someone else is using a G3. I don't see it mentioned much in this forum. I bought one 18 months ago for my pool and am very happy with it. I leave it running all the time. The kids jump on it while swimming and I have never had a problem with it. No broken hoses, dis-connects or any problems that concerned me. What I have encountered is that the internal baffle wore out after 9-10 months. The manufacturer told me that it was due to excessive clorination. Probably true as I only recently started using Bens test kit and following the recommendations from this forum. Another thing that I noticed was that as the baffle got older (worn out?) it started to lose the ability to climb the walls. A new baffle and the G3 was back to climbing. Down side is that they are around $30.
