They look reasonable but use watch batteries, yuck. I guess you could argue that USB rechargeable lights will eventually need replacing entirely when the battery dies, but I'd rather that than have to carry spare batteries.

Still, it's a good price for what it is I guess.

The USB lights tend to be primary lighting. These are great for just fitting and forgetting. As the light output is at a sensible level (rather than blinding) the batteries last ages!

Good to keep in your rucky as an emergency, if your main lights die. I have similar versions, and they have proved useful at times.

Trendz are pretty good, ordered for the first time a few weeks ago. £5 mudguard and it came next day with two free packs of haribos,

Yep they always tend to put in Haribo. Lol

For those who commute when its dark or during winter with a rucksack I cannot recommend this enough for a rear light.

There is NO other red light like it, mine has been Gorilla taped to two commuting rucksacks which have worn out whilst the light has carried on going. It's like a star has just exploded on your back, on the rucksack it shines down onto you, the back of the bike and the road, vehicles give you a much wider berth when this is on your back.

You need a couple of 18650's and a charger but it's well worth it.

These are pretty good for what they are. I've had mine a couple of years and just leave them on my commuter bike when it's left at the station. Batteries need replacing now but have lasted well.
