For a $200 box, it's probably fine if you don't have tons of tools and don't plan to use it on a regular basis.
Back in the late 90s, I bought a red Craftsman homeowner's box (top, intermediate, bottom). It was non ball bearing and had bars that went in front of the drawers when locking. It was my first roll around box and used it regularly for a few years, including professionally for one year. I had it waaaay overloaded and eventually the slides in the bottom box gave out.
I still have the box, but it's been retired to the basement workshop where it doesn't get used very often. If I would've used it as designed, it'd probably be in better shape today. I gave it an overhaul and now it works pretty well for occasional use.
My two cents on the box you're asking about...for a homeowner using occasionally, it's probably fine. If you're planning to use it on a more regular basis, I'd probably look at other options.
I will say that if you have a little more money to spend and can afford it, take a look at this HF box. It's a decent quality box for the money.
