I bought two grooming tubs for my grooming salon. 1 which is my lift tub . I paid a few hundred more on this tub then my other 50 in from Velour. The quality of the lift. It serves it purpose and personally my staffs back for the 120lb plus dogs. I thought I saw this one had a lock it does not. My door constantly slides open when I have raised, the entire tub shakes really bad after lifts up. It’s suppose to be rust free, yet second day of having avd washed out the night before has rust dots in the corners. The metal from the bottom has a welded very thin piece of support. When the dog gets out you see the thin sheet of a v from them using castor thin sheet laid down. It had a lot of dings, dents , and scratches all over the tub. However because I bought as I was building my new store I couldn’t just put it back in the crate and ship it back. I really wouldn’t recommend this tub as it’s about convenience instead of quality. This is my first owned lift tub. I did see other models prior in vendor shows so I assumed this was going to be awesome. If you don’t mind spending 1200 and having to go buy a child’s lock upon email I received. What’s more important quantity vs quality? Mines Safety. My dogs are scared to death. This will not last for more than a year to year in a half.
