Bought these anchors after I got the Rogue safety squat bar. I was tired of moving the barbell and the safety squat bar in and out of my rack. These anchors make everything SO much easier switch the bars. Darko Lifting is a GREAT company. I'm on board to fully support small businesses like Darko Lifting.

I preordered the Ibex x2 + lat arm back in August 2025. I was patient and it was totally worth the wait! Massive upgrade from cheap functional trainer I bought on Amazon over a year ago. The pulleys + bearings are silky smooth. I almost bought the Ares add-on but I wanted 1:1 ratio. The only 1:1 options were to add Dialed Motion Ibex or buy a brand new Dane 2.0 rack (which wouldn't fit in my low ceiling basement). The trolley system is very innovative yet simple, very smooth and love the wheels so it doesn't wear down the paint on my rack. The packaging was very impressive with the cardboard that perfectly fit the hardware. Loved that they were mostly recyclable (very eco-friendly household). As I was assembling this, it took me >2 hours because: My PR-4000 upper back crossmember would not attach the pulley mount because the upper hole could not screw in a bolt to hold the mount. Luckily I had an extra pull-up bar to replace it and it works well. I had to watch videos on how to assemble it. After I finished one side, the other size was a breeze. I worked a 12-hour shift before, lol so my mind wasn't fully intact. My wife gave me a beer on an empty stomach so that also did not help. Also, I noticed how much engineering and detail went into this product. I was simply amazed on how well thought everything was. For example, adjusting the trolley with washers so it can fit your rack so it doesn't have a lot of give. My mind was blown. Overall, I am SO happy with this purchase. The quality is top notch. James and Leland were prompt to answer questions about my order via Instagram. Now, I am waiting for the Roller Footplate to arrive!

I got these secondhand with my PR-4000 rack and I thought it'd be cool to use these. I used them for awhile to find out they are very cumbersome to set up for a 4-5 set workout. If you wanted to change the height and the placement of the arms themselves, it took >5 minutes to set up. You are literally sweating trying to position them JUST right for your exercise. I mainly used them for chest press, shoulder press, chest supported rows, and calf raises (with pull-up bar attached). I tried to do leg press but it wasn't the same. Then I tried to figure out how I can use these arms with the Dialed Motion Ibex functional trainer but I decided to take these down because of how much of a pain it was. Also the resistance curve was okay depending on the exercise.

These are amazing! We have limited space in our basement gym and as much as I would love to have a set of dumbbells (10-125lbs) they definitely could not fit. Selecting the weight is very easy - sounds and feels satisfying moving the selector pin. I've watched numerous review videos of people dropping these dumbbells and they are as good as advertised. The quality is hard to beat. The only adjustable dumbbell that competes in this market are the Powerblocks and Nuobell. REP has great customer service by sending a new pin to those who've had the old pin for the add-on 2.5lb plates without me knowing about it. Now that's what you call awesome customer service! I did have one issue with the plates getting stuck whenever I put it on the cradle. Luckily, I found out on Reddit that REP had a video on how to fix the issue and since then there have been no problems getting stuck. The ONLY con I have about these are the price. These are probably the most expensive adjustable dumbbells in the home gym market. I bought these when tariffs were initiated and it affected the price as it went up $200 from the original price. I was lucky enough to have purchased them before the next price hike. However, if you think about it buying 10-125lb set of urethane dumbbells will run you >$2000. So I can't complain.

Love my PR-4000! I bought it secondhand from Facebook Marketplace for a great price so I put 5 stars for value but I'm sure if I were to buy it new, I'd still give it the same score! It does well with what I need it to do. 3x3 rack helps with rack attachments but limited with the 5/8" holes. The safety straps and the safety bars are great options depending on what you want to do with them. Recently added on the Dialed Motion Ibex x2 with Lat Arm attachment for lat pulldowns. Overall, the rack does well for what I use it for.
