I've installed two (2) cogs and lockrings, both with the rotafixa and hammer+screwdriver lockring wrench. Both have worked fine.
ha! my local bike shop guy--the kind of guy who fixes things with hammers and duct tape--loves the hammer-and-something-else lockring wrench. i love it too.
this is a good time to reiterate proper cog and lockring installation:
1. grease threads.
2. thread cog on gently.
3. chainwhip or rotafix it on. get firm and strong on that mofo.
4. put a lockring on. tighten it, firm and strong again.
5. go for a ride. mash up some hills but apply NO backpressure (rely exclusively on your handbrake to stop).
6. stop and tighten your lockring again.
