This Unity XL grill cart is the third Keter product I've purchased. In case you care, I have the Folding Work Table (bought at a hardware store) and the 90-gallon Deck Box also. I'm very pleased with this company.As I was assembling the grill cart (with excellent instructions included and online), I discovered the metal top was damaged with significant dents. I immediately called Keter support. After a lengthy hold, I was greeted by a friendly and helpful agent who processed my issue and provided a replacement part without much fuss. Seriously, besides the hold wait, I spent more time giving my shipping details than describing the damage. Keter is amazing to work with.Now, the cart is sturdy. Most of it snaps together with the occasional fastener for good measure. Assembly was easy, but I take my time and am fairly organized when setting it all up. I took my time and only made one misstep, which was easy to readjust. The parts are all molded resin, so some of the snaps you're supposed to hear aren't as loud as others. I used a soft mallet to gently tap parts together once I was certain, very certain, they were aligned properly. On the negative side, there may be a little warping in some of the edges, so be careful when slipping one part into another. Also, the front doors are a pretty tight fit, but that is both good and bad, as you could imagine. One other thing I would add to it is a removable shelf (one side only) inside the cavity, but I can use shelf organizers to accomplish what I need, so there's no urgency to that request.The enclosed literature states how much weight can be put on each shelf and the totals will surprise you. The interior shelf holds 100lbs (45kg) and the top, metal shelf holds a whopping 150lbs (68kg). The spice rack even holds 12lbs (5kg)--that's a spicy cart! In short, it's sturdy, but not bench seating.
