I was reluctant to get these, as they are more expensive than the larger at home shop ones from Park Tool... but... i have used them a couple times now at home (luckily never had to use them on the road) and i was able to ise them easily w bicycle gloves (as they kind of hirt my hands to use without)
Very poor tool the handles arent long enough to get sufficient force to either seat or remove a master link. What you get is an exercise in frustration. Get the Park chain tool for 13 the cost.
I've been commuting with Park Tool's MLP-1.2 in my pack for years and have been looking for something clever to replace it with. Park Tool's pliers is great, but it's a unitasker and kinda bulky - now I can leave it in the shop and bring Wolf Tooth's combo pliers with instead. I'm usually riding a 10 speed CX bike or 11 speed fat bike, so having a dedicated spot for both replacement quick links is great. Fitfinish are wonderful and it's really entertaining to flip open & closed (slightly less annoying than repeatedly clicking a pen).
Now my MPL-1.2 gets to stay in the shop along with my VC-1 core tool and I just need to bring a single tire lever since this gadget will work as a second lever in the rare case I need two.
TL,DR. Pretty. Fun to flip open & closed. Works.
