During COVID my spouse began cutting my hair at home; the initial cuts were a bit embarrassing, but the mask hid my identity while outside, so no problem! Over the past three years, both the haircuts and her skill level improved. She isn't ready to work in the top salons in NYC, but I figured she at least deserves a decent salon-grade rolling tray. She just used it last night for a haircut, so here the the pros and cons of the assembly, quality, and practical use:1. ASSEMBLY: There are only 10 parts, so it's not difficult, the only tool needed is included which is required to screw in one bolt and washer. The included instructions include pics, but the wording is poorly translated with a few unintentional hilarious statements such as "it requires our human body push in the wheels vigorously with our hands". Seriously though, I put it together in five minutes, you can too.2. Quality: All of the structural pieces are welded together (See photo 1), so the unit is strong and should last years from moderate use. The wheels have foot-enabled locking brakes and are fairly well made, I wouldn't roll it down hospital hallways every day, but it should be fine for moderate salon and office work.3. Practical use: The tray is large and gravity fits into a tubelike frame, it doesn't have any snaps to hold it in place, but seems to provide a reasonably secure fit for multiple instruments less than 5 lbs. I placed some salon shears, brushes, and clipper attachments on top (see photos 2 & and 3) so you can get an idea of the scale and surface area.Overall we are happy with the unit and give it five stars. No, it's not a heavy-duty AMA-approved hospital-grade device, but for this value, it would be a great buy for a salon, for light clinic use, or at home for hobby work.PHOTOS INCLUDED: 1: View of Welded joints on base 2.
