The telephone Customer Service staff are extremely helpful, and are 5 star. I had a small problem in ordering a dimming set of LED strips which on arrival did not work. Sent back foc and the dimmer was tested and found faulty. Replacement arrived quickly but again did not work. It turned out that I was not using a sufficiently high wattage load with the initial strip ordered to enable the dimmer to operate correctly. At the ordering time the staff had not been made aware of the limitation, nor was there any note on the internet screen. I suggested using a higher loading strip and that in view of the fact they had sold me a system which could not work, that I pay the difference in the extra cost of the more expensive LED strip. The young lady on the phone then referred this suggestion back to their manager who REFUSED to make the commercial decision to swallow a loss of about £4-£5 in an effort to keep a happy customer and future goodwill. I would have given 5 stars if it was based on the phone personnel but the stupidity of the manager in ignoring customer goodwill results in the lower score.
