Pros: --Holds the weight and size of a Panda 3.5 dryer and Black Decker 2.0 washer. --Comes with all necessary tools including screws and screwdriver and predrilled holes. --Rolls over carpet with ease --All bars connect. There are holes to guide you so that the bars connect evenly. Cons: --Some of the screws are very difficult to screw in using the screwdriver it came with! I ended up with a blister on my palm from pushing down hard on the screws while turning the screwdriver. -- I don't think the blue liquid leveler is necessary. It is a pro and con because I'm afraid they will pop in the future and make a mess. Tip: --Use a towel over the screwdriver so you don't get any blisters. --Before purchasing on Amazon, check out their website to see if it is cheaper over there. I first ordered this dolly on Amazon because it was the cheapest I could find, but the delivery was going to take two weeks. I tried to cancel, but Amazon wouldn't let me. I needed one right away, so I checked Vevor's website, and they were selling it the same price as Amazon with free shipping! I ordered it on their website, and the dolly arrived the next day. It was a win win situation because I got one for my dryer and one for my washer. Hope my review helps!
