Summary: Body of light has improved, but mounting strap is flimsy and sticks out 3/4 inch.
I have owned a very similar Cateye model in the past that I really liked. So I thought that it was a no brainer to get the upgraded model for another bike.
The body of the light is a slight improvement with an easier to reach button and it seems to be a bit more weatherproof.
It is average in brightness. For those who ride alone at night, you might prefer something brighter. But for early mornings, especially when your with a group, it is bright enough.
However the strap Cateye switched to is flimsy and is hard to tighten down. After one ride I noticed it loose.
Furthermore, the end sticks out 3/4 inch. I prefer the tail light mounted vertically and you cannot do this if you mount it on one of the stays. So I had mounted it on my seat post. The end rubs up against my leg as I ride which is very annoying. The older model had a much more secure mount and did not stick out more than an 1/8 inch.
If Cateye goes back to the older mount then this would be a good tail light. But I have taken it off my bike and replaced it with a Planet Bike Superflash (hopefully the Superflash won't annoy the friends I cycle with for being to bright).Get more detail about Cat Eye Bicycle Tail Light - TL-LD610.
