I have this half rack for a half year now and I still love it. It's very solid mine is not bolted down and it only moves a centimeter when I rerack a 150kg bar (and thus most of my weights are not on the rack anymore). I believe that if you would have some big plates on the rack it doesn't even move reracking from a 200kg squat in its unbolted form.
If there is one thing I would change about this rack, it would be to put some additional holes at the bottom for band pegs (like the riot multi station).
I also use various bands, gymnastic rings on this rack to mimic all kinds of other different movements. Attaching bands to the rack at different heights mimics a great pulley system (the bands at Strengtshop are also good quality).
P.s. customer service is world class
