Review on Maxspect Gyre XF350 Spare Pump: Optimized Wavemaker for Enhanced Flow by Rose Washington

I have ordered a total of 4 controllers and 8 XF-350 pumps. Of these, 2 pumps and 1 controller failed and were never switched on. And 2 weeks after using another set, 2 pumps and 1 controller stopped working and never turned on again. This is not to mention that the other 2 stopped working, but the new firmware installed got these 2 working again. So if you count these, 6 out of 8 controllers had problems! The bounce rate is 75% but luckily she has achieved an amazing 50% bounce rate. CoralVue tried to help but after 22 emails nothing was done. In about 16 of those emails we simply asked for receipts and retailer addresses, where, when and how I got the devices, they obviously didn't care about the wrong things anymore. Bottom line, maxspect is unhelpful and their support team is made up of native Chinese speakers, Coralvue steps in to provide services in English and they have not been successful in any way. For a Chinese pump with such a high failure rate, they still charge a lot of money for something I'm still interested in. I would seriously avoid.
