1.3" LCD Electronic Bicycle Computer/Speedometer (1 x AG13)

Pros: It works. If functions properly. And, it's actually waterproof! I tested it on purpose and held it under a crane for a minute.
Still worked. The quality is pretty nice, not something i expected.

Cons: Packaging is really poor. Looks like flea market packaging; i ripped the so called 'blister' packaging with one tear clean off.
The manual is, plain, horrible. It's best to have some knowledge about LCD hardware in general before buying, or just take wild guesses about what to do. I did.

Other: I your looking for a bike computer, or even better; something to display time on your motorcycle, this is your choice. Just hook it up on your handlebar, cut off the cables that are destined for a plain bicycle, and your good to go!

Pros: Cheap, easy to use (that doesn't apply for mounting), and after you finally manage to mount the sensor (see the cons part), it works fine. I'm using it for more than 6 months now and it seems to be pretty resistant to any weather conditions, even rain.

Cons: The manual is terrible, it's close to useless, had to figure out almost everything on my own (which wasn't that bad, the logic of the computer is pretty straightforward). The mount of the sensor is made of extremely poor quality "rubber", it tore apart on the first mount attempt, so i had to use cable fasteners to mount it.

Other: It has some flaws, but still a decent buy for this price.
