My Review for the Rogue Monster Lite RML-390FULLW Fold Back Wall Mount Power Rack

Does what it says, but the compromise is real

 So, the good: when folded, it's tiny! It takes up so little space, it's amazing. And then it unfolds into a full power rack. This is awesome. The custom color looks amazing - I love the blue.

It's very easy to fold in and out, taking less than a minute total. It takes more time to move the barbells and plates than it does to fold the rack itself. The other reviewers talk a lot about how great the rack is, so I won't cover the positives as much here.

Let's get into the downsides. You want a compact, convertible thing? You know there are going to be downsides.

The installation is annoying. The measurements you need to make are very precise and painstaking - the rack must be perfectly level, and there's not much margin for error with the included bolts.

If your floor is not perfectly level, then you need to use spacers to ensure that the rack feet all touch the ground. However, this means that you're going to be applying a lot of pressure when the feet are pulled in. Rather than putting spacers under the feet, it's better to add spacers under the rubber mat or flooring to level it out.

The rack isn't entirely stable. It sways side-to-side slightly. The pullup bar is the only thing giving it lateral stability. The rack is also quite wide, so you're probably going to hit the vertical supports when walking a squat out, causing the whole thing to shake a bit. It's not a huge problem, but it is unnerving.

The rack is right next to the wall. It's uncomfortable to setup for a squat with the J-cups against the wall - my face has maybe an inch of clearance. If I had a longer neck, it'd be really awkward. Fortunately, you can put the J-cups on the outer supports, but then there's very little room for a spotter.

Unfortunately, there's no good way to bench. If you are very short, you might be able to put the J-cups on the outer support. At 5'10", I'm too tall to do that. With my head pointing towards the wall, there's really no space for a spotter to provide adequate spotting.

I had concrete at the bottom of the wall in my garage, so I had to raise the bottom stringer, which means I need to also raise the crossmembers. I can't deadlift in the rack now. It would be nice to only need to raise the stringer supports and keep the crossmembers low.

If you absolutely need to be able to save space, then this works well enough. Unfortunately, I realized after installing it that I didn't need the folding ability, and would have had space with a full stand-alone power rack that wouldn't have any of these problems. 

I'm giving it "1 star as a $1300 power rack" and "4 stars for a compactable power rack," averaging out to 2 stars. If you can possibly have enough space for a regular power rack, save yourself the $700 and get an R-3. If you don't have space for a power rack, strongly consider squat stands or the even-smaller wall-mounted options. At $1300+, it's a huge amount of money to spend on something that just doesn't work great.
