The box arrived in a timely manner and was delivered to my front door. The instructions are clear, the parts are well marked, and extra bolts were included as a backup to assembly. The caddy fits perfectly in the spot needed and adjusts with little effort for either right or left hand mouse use. The wheels lock, which adds somewhat to the stability against movement and the height is easily adjustable. All-in-all, I'm pleased with the purchase and didn't have to wait for my husband to come home to assemble - I did it is about 30 minutes. Always enjoy shopping at Overstock. Thanks much!
