I purchased a CPSC-24AG in May 2013. It was replaced 5 times last summer for issues ranging from no display to melting wires on the cell. Finally, Compupool replaced it with a CPX-24AG after waiting almost 4 months for them to get a CPX unit in stock. I installed it the beginning of June and the new unit has had no issues until yesterday. I went out to check the pool and noticed the pump was not running. It trips the GFCI as soon as it is plugged in. I contacted Compupool and they are going to replace the powerpack, but...they don't have any in stock. They possibly may have some in stock sometime in August. I understand all things will have problems, and they have been good at troubleshooting and handling the warranty claims, but their turnaround time takes weeks to months and they rarely have parts on hand. After this, I definitely would have chose a different brand. Looks like I better stock up on the bleach, I'll be needing it for a while.
