Slackers Portable Slack Rack - Indoor and Outdoor Slackline for Improving Balance and Fitness - Adjustable 6 to 12 ft Length

This thing is super well-made, very solid, easy to set up. The only criticism I'd give it is not the actual mechanism itself, but the tiny, tiny, miniscule print in the setup instructions. I mean, seriously (first world problem, for sure), the print is so tiny that it took longer for me to read the instructions than to actually set it all up--and I've got sharp vision. I'd sincerely encourage the manufacturer to include the instruction sheet in a 12 pt. font, rather than what looks like a .05 pt. font. It also wouldn't hurt to enlarge the photos.Other than that...this rig is awesome!

Having this in our loft has been a life saver during quarantine. It was easy to install - we use it with a 12 ft 4x4, sanded down since it’s in the house. It took a few try’s of slowly ratcheting it down to get it tight enough without over ratcheting, and you’ll get some major creaking and cracking when you first use it but that went away after the first day once it settled and we haven’t had to re-tighten in. We’re both around 150 lb and I don’t see ours standing up to someone much heavier (say, 180+). Overall, super pleased with the convenience and simplicity.

This thing is just awesome fun for the whole family. Great idea and well executed.👍

I weigh 185 lbs. and feel like I'm at the real weight limit (the product description says it can handle over 200 lbs.). When it's set as tight as possible and I stand in the middle the slack line is just barely above the wood beam. I use a 12 ft. beam (the maximum) - I think any smaller wouldn't really be much of a challenge. I got the hang of it in about a week. I also noticed that the slack line started to fray where it enters the tightening mechanism after only about a month. Other than that, it's pretty fun and a good little core workout/balance improver.

Great set up! It provided hours of fun in my house during the Covid 19 quarantine. I would recommend.

Base wobbles!

Perfect for inside with the kids. I’m 175lb and the line touches the 4x4 when I’m on it. The instructions are terrible but it’s easy enough to figure out

I bought this for business use in teambuilding/trust activities. I was looking for a slack line that gave me the option of using it indoors or without trees. This fit my needs, and was a more affordable option than others I've seen. It worked well, but I could have used more detailed instructions. It seems durable, and I'm looking forward to years of use.
