I have many Hue products. Including many of these. While clearly they are over priced for what they are, the system does work well. With the system limitations taken out! Unfortunately there does seem to be a manufacturing issue right now with the cutting point markings being in the wrong place, cutting them damages the light causing some of the light to fail or have problems with certain colours. I ordered two which the same problem happened. Its not an error on my part, I have installed many of these already with no issues. On closer investigation I could clearly see the cut line was off by around 3mm - 4mm, hence cutting causing problems. The danger here is you may have issues with warranty claims where you are blamed so something to be aware of. Potencially great product, but should be £5 cheaper minimum for what it is.
