Welcome to the forum, good timing as the Mirafit M2 power rack just came back in stock and i was going to ask if anyone has one and what their experience with it is. I had pre ordered the strength shop thor power rack but that 100 quid more.
Thanks for the welcome everyone.
The M2 is a solid unit and the pulldown and low row are really quite smooth. The only issues I have with the lat/low row are that the low row is attached directly to the bottom cross-member so you are pulling up at an angle - I'd prefer it to be raised 8-10 inches so it was a direct pull to midsection. Obviously secondly the plate loading I find annoying, especially when doing shoulder work.
I haven't bolted the rack down and it is stable. I'm not squatting huge amounts and don't use the pull-up bar, so ymmv. Bear in mind that there are a lot fewer compatible attachments for these 60x60mm racks than those based on Rogue dimensions. If everything you want is sold my Mirafit, that isn't an issue.
I hate my safety pins. My garage is just 8ft wide so there's very little space around the rack. I'd much prefer drop down safeties like the 360KG model has for ease of removal so deadlifting inside the rack was more convenient. Mirafit couldn't tell me if the 360KG safeties were compatible and even if they are they don't sell them as an aftermarket upgrade. This also comes on to the hole spacing. It is 3" between hole centres (I think) which is inconvenient for me in the bench area. The ideal place for my safeties is about an inch above the "next-best" holes. They still protect my neck/face completely but if a heavy bar slipped out of my hands I'd take a big hit to my chest. Same issue with the holes for the j-cups - ideal position is right in between 2 holes, so I have them in the upper hole for now. I'm planning on drilling new holes for the j-cups this weekend.
I didn't really take these things into account when buying the rack. I bought in a bit of a panic right before all the gyms closed. I was comparing prices and heights of racks (low ceiling) for about a week and then noticed everything selling out, so I jumped on the M2. I was originally planning on buying the Strength Shop Garage Cage with westside spacing, but it sold out.
I'm not unhappy with the M2 as it was a good price, relatively simple to erect (solo) and is perfectly useable as-is. Once I've sorted the hole height issue it will be much more user friendly.
The 360kg model has the same issues with the hole spacing and low row height but comes with the drop-down safety bars, so I'd certainly consider that over the 250kg model.
