We had the F-220 tube, the first was under 100w no where near 220W or more advertised, then it fails within 3 weeks, they replaced it with a second faulty unit, which due to the shipping and installing was over the 300 days warranty. On the website is stated that the warranty is 300 days from the date it leaves the factory, the date on the tube was 15-7-15 and we reported the fault when that tube was 223 days old, yet they would not replace it. so that's a 200% fail rate on the tube. When we arranged to purchase this tube they showed us images of a metal encased twin tube with integral first 45 degree mirror, what we we sent was a nasty and poorly constructed tube that was covered in what I can only describe as white hot melt plastic, which seems to be all that holds the 2x45 mirrors at the end of the tube, so even if it did work the alignment issues would be questionable due to the poor engineering and construction. To rub things in they did offer me the MkII tube at full cost.........as If I would throw more money at such a disreputable company. Nothing to hide here, if you want the photos to show all the evidence they are available, just contact me.
Sorry dont have them any more, but They didoffer a cut price replacement tube with a new model Mkii or Mkiii which worked great, output 285W, so all ended amicably
A Chinese company not delivering what they promised? Who would have thought. Would not be surprised if the CCP found a way to attach a bug to steal the customers proprietary information once installed.
@@heavycurrent7462 He has never been to China. However I have working in manufacturing in China. In the 1990's yes factories were a mess when I first went to China in 1992. In total I spent about 10 years in China and factories today are much different than before as they are modern and clean. Small factories for cheap product are still messy though, same as in any country even America.
