Good system. Only issue I have is the cables. They aint designed for everyday use. My cables split and messed up in the first 6mths. The cables if snapped can cause major injury. Other than that is a very functional system. Definite end to purchase additional weights if your a heavy lifter as well.
Feels and works like magic, the pictures don’t do it justice. Thanks team @Cardiooline :)
The Cortex SM 20 is a definite must have for any garage gym. Easy to put together and great quality. It fits neatly into a small area yet boast the best workout ever. Worth every cent!!
I received this around 3-4 weeks ago and wrote a previous review. All issues have now been solved in a timely and stress-free manner with staff. The machine is now 100% built and functional. It is overall a fantastic machine for the low cost. As expected, the cables do twist when setting up but after straightening them out, they work well and stay on the grooves at all times. This is a really good all-in-one must have for a home gym. The cable height adjustment is more comfortable than conventional sliding ones, this one allows you to take it off completely and set it in. The smith runs super smooth and all attachments work well. I would buy again despite previous issues as the machine is awesome
Bought this 3-4 weeks ago and wrote a previous review named "Monique". All issues have been resolved and the machine is not 100% functional. Overall, this product is a bang for your buck and works like a treat. Best part in my opinion is the design of the cable that attaches on the rack. It allows you to take it off and lock back on instead of conventional sliding design, which means it does not get stuck. Smith is super smooth and the cables run well and stay in the groove. I would buy this product again despite previous issues, the machine is just that great
Great piece of equiptment, smith machine is smooth and only took about a day to assemble. Only issues are the cables feel a little bit stiff when using, and i am unsure why the weight stack is in pounds, not kg. Other than that, good rack to have.
Bought this last week and just put it together after a few days. Could start building alone but eventually you need another person. Build quality is what you'd expect for the low price but I am satisfied with it. Unexpectedly, the delivered parts inside the box gave me 2 left side Smith safety racks so only one side has a safety bar attached to the frame. Also the attachment to put on the landmine came broken as you can see where the welding gave way for it to split. Quite disappointed to see that not one but two parts were wrong/ faulty despite being in the box and sealed on delivery. I will be calling to see what can be done for the faulty parts
Quick delivery, easy to setup. Have setup in the garage, looks tidy & is very functional
Bought this Machine a month ago but have only just gotten the ability to use it, Feel like the 100kg weight stack is a mis-direct, because of the mechanical advantage provided by the pulley system, if you only use 1 side of the rig at a time, you are only lifting 50% of the weight, so fully loaded at 100kg is only putting 50kg strain on each side of the rig

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.
