Rear Bike Light 90hrs Autonomy - Compact Size, IP65 Waterproof, USB C Rechargeable, Quick Release Mounts for Saddle & Seatpost, with 5 Steady Flash Modes, DON PEREGRINO M2 Bike Back Light

The media could not be loaded. I bought this M2 in July 2020. Used it for about 3-4 hours per week on the Flash mode. Battery is excellent and better than any other rear light I've had. Other rear lights (the long thinner ones) lasted about 3 hours in total.It says you'll get 90 hours of use from using it on Flash mode. I can't vouch for this, but I can say it has gone on for over 15 hours before I've charged it - and not because it has gone out, but because I didn't want to risk it going off on a ride, so it could have gone on for many more hours.The brightness is perfect. Something about the LEDs' arrangement and the translucent white cover just make it very catching on the eye, particularly on Flash mode.The strap is clever. It has two asymmetric rubber pieces on its inside that mean when you attach it to your seat post, it sits nearly vertically, rather than at the same angle as your seat post i.e. slightly downwards. This is great for visibility.Some people say the plastic clip on the strap is prone to breaking, or that it's difficult to put on and take off. At first, yes, it's a bit tricky because the clip is separate and it's small so you might drop it. But, once it's in one side of the 'rungs' of the ladder-like strap, position the light on the post, pull the other side of the strap around the post and slot it into a rung. You can pull very hard on the rubber - it's pretty thick but also stretchy. It takes about 15 seconds! Also, the clip has never broken, even when the rubber is very tense.The only possible issue is that the plastic clip will touch part of the seat post, hence if your post's paint is thin, it may cause a mark. You can simply put some gaffer tape on the flat bits of the small clip. I haven't - and I've noticed no marks on my seat post. Not worth the trouble for me.I recently ordered another M2 in December 2020, for a recently acquired second bike. Highly recommended as a rear bike light - in fact, don't bother browsing other ones, just buy this one now!

Good lights. Fits well. Bright. Good battery. Seems well made (I've had it many months now).

This light is easy to fit. It has many different settings which you just scroll through. It is rechargeable. Good value for money.

Good price very good combination of light settings for a rear light 2good fittings under seat best for view from approaching cars

Excellent value for money and super bright, easy to mount to bike, definitely recommend.

Bright and lots of fixings. Only a spare for me but more than up for the task of the daily commute.

The light is brilliant , now the big but .The fitting is not fit for purpose , as you put the light in the holder & turn to lock it in place but it’ doesn’t feel secure so when riding your bike, the vibration loosen the light and it falls off and you have no cule unless you hear it, and that’s the end of your product so for that reason I give this product one at best, but I recommend for those reasons you don’t buy this product as you’re just throwing your money away.

The light is bright, easy to attach and it stays in position.It has also run through bad weather without any problems. However, the battery life on the standard setting is less than ten hours. There is no warning of a low battery, it just switches off. This is less than ideal when you are road riding and you have no idea that your light is about to fail.
