I like this computer because it does NOT have 8 different modes requiring a bunch of button presses to find the info you want, causing you to crash into a tree. It only has 3 modes: time & temp, max & avg speed, and odo. The top 3 lines - speed, ride time and distance - are always the same, and switching between modes only changes what's on the 4th row. Lots of info at a glance, but simple to use.

The white color is hideous, but necessary since it has a built in thermometer. Even in white, it will read high when it's in the sun (duh), but when it's not in the sun it IS accurate to within a degree or two.

I've had several of these. One has failed outright and another one got permanent discoloration in part of the screen because I left it on the bike while it was parked outside in a rainstorm. PB replaced one of them when I asked; the other one I just live with. It is mostly but not quite fully weatherproof, so caveat rider. Do NOT leave it on the bike if you're transporting it on your car; if you encounter rain on the drive you'll probably ruin it.

One other downside is that despite a larger, heavier magnet than Cateye computers, you have to get the pickup REALLY close to the passing magnet for it to sense it. Like no more than about 1mm away. Not sure if this is going to work on my fatbike without modification - I may have to rig up some sort of block to stand the magnet away from the spokes (or the pickup inboard from the fork leg) in order to work.

Pros: Awesome interface and screen. All the important info visible at a glance, with less important info visible in just 3 modes with no submenus. Keeps your eyes on the road, not sifting through your computer's menus and modes. Has a thermometer!

Cons: White is ugly. Pickup is not sensitive and requires the magnet to pass really close by, causing compatibility problems with some fork/wheel combos. OK in moderate showers, but not fully weatherproof.

This computer worked well for my 1200 mile tour a few years back. It made it through the whole thing and came back alive, however the white did discolor from the sun. I'd probably get a black next time, but it'd be the same brand.

Nice look, functional

This is a decent computer, with a lot of info that's easy to access with one button. To press the button, you push up on the computer, and it slides in the bracket. So you don't have to search for a little button while pedaling.

I have a bike with white bar tape, cables, etc. So finding a white computer was a nice aesthetic plus.
I had to get a wired model to work with my tandem.

Pros: Easily readable display, with just one button function.
Comes in white.

Cons: Initial setup is a bit of a pain.
Pressing on the casing to use the button sometimes makes it slip.

Great computer

I have four bikes with different computers on them and this is by far my favorite. It has all the functions you need on one screen and no buttons to fool with, just push it forward and it changes screens. I have been using this on my mountain bike now for 3 years and have had no problems. I had read other reviews that this is sensitive to water, but I have had no problems with it. I usually stick it in my pocket when I wash my bike just to be safe.

Pros: Price
Simple to use

Cons: None that I have found yet
