I'm very impressed with this given the price. Shipping was very fast and the unit was well packed in a wooden box. There are some minor scratches to the black finish on the underside of a couple of the shelves, but nothing that a bit of black paint won't fix. It looks very attractive when put together, especially if the majority of your av equipment has the now-popular gloss black finish.
Assembly took about 15 minutes, and that included deciding how much space I wanted between each shelf (note that you can re-arrange the shelf support tubing by size to any order you want - for example I have the largest size tubes right at the top to accomodate my amplifier/receiver, which sits right underneath the tv). To be honest the unit has a reassuring weight and sturdiness to it, and mine is comfortably holding a 37" tv, amplifier, blu-ray player, sky box and dvd recorder. The width of the unit is perfect.
I didn't even need a screwdriver to put it together, a supporting rod runs from the top to the bottom of the unit and screws in tight once the feet are on. I know the unit is pretty heavy but I managed to unpack it, put it together and then carry it up a flight of stairs myself so as long as you're a pretty fit kind of person you shouldn't need any help.
I'd recommend this to anyone considering the price. A couple of niggles as already picked up in other reviews - the cable tidy is useless (you can't fit a decent quality scart lead through it without cutting another hole), and the stickers marking the top side of the glass will need something from ICI to shift by the looks of them. Neither of these points should put you off though.
