Reviewed by Ania - 7th Jul, 2017 Great device I have been using the Matik for the last couple of months now and am very happy with it. It does the job very well especially with the thin ropes. Perfect for those that use ropes between 8,5 to 10.1mm. I would not recommend it if you use the 10,2 or thicker as it keeps jamming. The anti panic function is very useful especially if you have much heavier partner than you. It's impossible to clip it wrong way so your climbing buddy doesn't have to worry when climbing. I bought it because it's the only device that let you do dynamic belay and it does the job very well. Matik works on the same basis as ATC device so it very easy to learn how to use it even though the description on the packaging is very poor. I would definitely recommend this product especially to new climbers.
