Pros
- Lights are amazingly bright, you will definitely be noticed on the road
- Both lights use 2 AA batteries; I use rechargeables so this is great
- Simple design, very easy to use, to attach and take off again
- Do not need a clamp to use them
- Lights seem to be very stable when attached

Cons
- In my opinion, the front white light is much better than the rear light. It seems more durable and attaches much better to the bar.
- As everyone else said, the on / off switches are far too sensitive. If you put them in a bag, you WILL accidentally switch them on eventually. This affects both lights but the rear light seems much more sensitive.
- Rear light: parts of the silicon casing look fairly thin, and as you need to stretch it a fair bit I am not sure if it will last a long time before it breaks. time will tell
- Rear light: The way it attaches does not seem as stable as the front light. It is a bit trickier to make sure that the catch really locks in; it seems like it would be fairly easy to not attach it properly and then have it fall off over a bump.
- Frong light: the light is highly visible to the rider. Some people might find this very annoying; I don't mind it so much, it lets me know the light is still on! Perhaps knog could have designed it to not be so visible to the rider though.
- Occasionally, if you hit a large bump, the lights may switch modes on you. I think this comes down to the super sensitive switches again. This seems to be a common problem with bike lights, and while its not so bad on these ones, it is still there.

Conclusion
These are great lights, not without their flaws, but overall I love them. Would I recommend them / buy them again? Yes.

Excellent bit of kit. Very bright. I have the USB version and bought these AAA battery version (by mistake) for the wife. Still great. In reply to the comment below about the front light blinking white-red-white-red: that's the "low battery" indicator not a fault! Change the batteries (or charge it if USB version) and you're good to go.

We bought two sets of these lights and have had nothing but trouble with them. They come on by themselves and the switches are very poor hard to use. Its a shame as they are such a cool product. I've heard there is a recall but don't know whether thats correct or not.

FRONT LIGHT - Great - Easy to attach and remove from handlebars, on the minus side the brightness causes glare in eyes, remedied with some opaque tape on top edge of lens.

BACK LIGHT - Nice and bright, on the minus side - AWKWARD and fiddly to attach!

Agree with all the negative reviews on here. Have had a couple of knog front lights and they have always been hopeless. It is a shame as they are so convenient to affix to your bike. Would strongly recommend you don't buy.

my front light started fine but after a few weeks it blinks white and red(!). Like white-red-white-red-white-red. Overall you need to press the buttons three times until it 'gets it' and I'll try and return mine. Shame as it looks like a quality product, but had nothing but trouble with it.
