Honest opinion without getting butthurt? Nope. It appears to be, at first glance, Chinesium. No certs, the teeth appear to be chromed? and slippery, the side is stamped 100kg max but the features says max load 24kn? heck that's more than a ropeman which is a tested device, and this takes the cake:
"climbing grabs rope grab rope grab fall protection rope grab lanyard rope grab ascenderrope grab climb right rope grab heavy duty"
That looks like someone went to the craigslist school of bad posting. No thanks man. Stay away. A climbing device is NOT the place you want to save costs. Save your scratch and get a ropeman or Kong. Or heck a friction hitch. Just my thoughts.
