only issue I had was me being a dumba$s and not connecting the 4-pin things the right way, so make sure you connect them so the little arrows are together. other than that they're great, might need a bit of backup stickytape but the colours are good, the remote's easy. (to do the diy ones you have to make all the colours 0 first by holding down the down arrows until the lights turn off, then you can put them up to customise.) came exactly 1 week after i ordered them (i live in sydney). i've heard that some similar products stop working after a couple weeks sometimes so i'll lyk how it goes.
