Almost 4 star. Built better than the previous 'stock' rack for sure but I found drilling out/sanding at least 1/4 " from the bottom of the top bar "holes" let's the bar sit a smidge lower ( see pic )and helps keep discs from being too difficult to take in/out from the top tier. Seems like an adjustment they could make at the source and those bars don't always seat perfectly it seems from message boards. Also found wrapping and glueing some 'soft' material around each bar, like shelf covering, will quiet it down quiet a bit. Would be nice if it was built that way or was an option at least rather than DIY. Otherwise it is built noticeably better than the previous or stock? version. Just can't justify 4 or 5 stars. Also must mention, take into account what time of the year you may be buying this. Not part of the review and not considered in my rating, but... I was a little bummed GGGT put these and the other 2 Zuca accessories I ordered on holiday sale 2 weeks after I bought them and would not refund the difference of almost $40 or offer me anything at all to compensate after reaching out to them . My fault I know, and I could have been a dick and just asked for a refund and got someone I know to re-order at the discounted price, but I try not to be a dick. Still mentioning it here to make me feel a bit better at least, sometimes ya just gotta get it out. I still love ya GGGT . Sales happen and sometimes we miss out. No harm no foul :)
