Fringe Sport has been on a tear recently with new product releases, and the BOB is no exception. I've had mine for 4 months and have used it across various exercises, and frankly, it has been a great addition to my set up and I'm very pleased with it. I own the PR-5000, so I was initially torn between the Rep Smith attatchment and the BOB. Ultimately, I went with the BOB because of its price point, the ability to bring my own barbell, the additional ROM at the bottom, and smaller footprint. One thing I was pleasantly surprised by is the ease of swapping out barbells--though, in everyday use, I tend to just leave a spare bar installed at all times. Personally, the few concerns I had --the "lateral deflection" and the seams on the rods catching on the trolley--do not impact practical use. Admittedly, in much the same way that adapting to a new movement pattern can be awkward, the deflection does feel a little odd the first time you use it, but that feeling quickly dissipates within a few sessions. Similarly, it's impossible to feel the seams on the guide rods when the bar is loaded and you are trying to achieve a training stimulus (which is the only time it matters). Frankly, unless your job is to review equipment for a living, or your gym is more of a showpiece than a means to getting strong and jacked, these potential "shortcomings" aren't really worth worrying about. That said, if I had a wishlist for the BOB 2.0, one thing I would add are hooks that attach directly to the trolley itself. Though bar-swapping is relatively painless already, this design enhancement would just eliminate the need to store the hooks separately, making it even more convenient.
