The size and weight of the mag board is great. We always take them to the crag to warm-up, and they're so small we didn't even think twice about bringing them to Europe with us. They're really well balanced so you can hang easily from a tree or bolt, or just put your foot through the loop and pull.
good
good but plenty better on the market for price
its not a bad product feels a bit cheap though I think ill go with resign moulded from now on
Topp
I love how small it is and how i can practice at my desk while im the office!
I’ve been using this product for months and I love it it’s so easy to set up and helps me get some finger training in no matter where I go so I can always come back climbing strong
I actually bought this for my boyfriend as a birthday gift, hes someone who trains his grip often before climbing and he loves it, very practical and great gift for yourself or someone else who climbs
I tried to find this product for so long lol, finally to be able to record myself climbing normally
Pretty cool board, can be put in my chalk bag pocket and use any time any where for training and lifting.
