Purchased the RTM Wall Mounted Pull Up Bar from Cardio Online. Compact, easy to install product with great functionality. Rated up to 150kgs, I'm only 80kgs and the quality feels all good - but would probably not put much more than 100 - 110kgs onto the bar. Good grip padding and ideal for a home gym. Would recommend it :)
It is a great product
I am using it for 4 days now as I received it last Saturday
It helps me to be active
It's been 3 days and everything is good so far. Shipping is good too.
Shipping was brilliant. The gentleman was wonderful and very helpful in getting it off. My husband assembled it, and everything worked and looked great.
It’s good so far. I’ve been using it for three days now and it’s fitting well into my routine.
