This lock is perfect on my commuter. Ride up and quickly lock the bike to run into the store. I never have to remember to bring the lock because it's attached to the bike. It's easy to use. I don't fumble around with it like I have done with my other locks.

I also purchased the 150cm plugin cable. It makes attaching the bike to a stationary object a breeze. If you buy this lock I recommend the 150cm cable as well, as it comes with a mounting bracket for your bike.

The reflective surface is actually plastic, so they are relatively lightweight. They do look better, and are perhaps more aerodynamic (not that I'm a super speedster), than a big round mirror jutting off the end of the handlebar. They also adjust nicely. I think they are about average on their reflective performance. The package contains two mirrors (left / right) so that's nice.

The injector is great. I can inject Caffelatex directly into the tire without removing the valve core.

This means I can inject the tire sealant directly through the Schrader valves on my wife's cruiser.

NOTE: After you use the injector you should push water through it so the valve nozzle stays clean. Otherwise it can get gummed up.

There are lots of reviews online about tubeless and Caffelatex. I just wanted to add my own 2 cents about using this sealant in tubes.

I've been using Caffelatex in the tubes of my commuter for about six months now. Not a single flat!!! Before Caffelatex I would get at least one flat a month, usually from a broken piece of glass.

Another benefit with my tubes, is that I only have to top off the air in the tire about once a week (instead of adding air every other day).

I highly recommend this product for tubes as well as tubeless.

This product works really well. Cars give much more room when passing.

Bought something very similar or the same in Germany 25 years ago. Used it for a long time until I lost it. Really works! Cars give you more space.
