Incompatible Hot tub cartridges, very reluctant to refund
Fraudulent company. Do not risk it. I ordered a 4-pack of cartridges based on website assurances of compatibility with my HotSprings Spa (2019 manufacture date) with Freshwater salt system. The cartridge did not function at all, the spa was unable to recognize it and shut down whenever I left it in place. The spa still recognized my old Freshwater brand cartridge. GP Filter required me to run a number of testing scenarios using several of the cartridges, but eventually conceded that the problem was not my spa. They then offered me a 50% refund, gradually increased to 80%, and to keep the cartridges, encouraging me to sell them on to other (ususpecting) customers! When I insisted on their other offered option of return of the cartridges they insisted on charging a 20% fee because one cartridge was "used" and could not be resold (an obvious contradiction of what they had been telling me to do)!! I still have recieved ZERO refund and no means of returning the cartridges, after 10+ email exchanges with "customer service." ADDENDUM: after all of the above back and forth, they finally agreed to refund the original purchase price, and still instructed me to keep the non compatible cartridges. Refund has credited to my VISA 3 days after their email stating it was issued. They promised to change the compatibility statements on their website. I’ve not checked.
