At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Good scores are more common than bad, because fortunately good products are more common than bad.

The Knog Blinder Mob V Kid Grid Rear Light is a great little unit that emits more than enough light and also has some good design features.

As the name might suggest, the Blinder is great for pumping out light – 44 lumens to be precise, which is more than enough for riding at night. It has five different sequences: two solid settings (one brighter than the other), one flashing, one with a jazzy concentric LED flash that speeds up and then turns solid, and one with concentric LEDs. It might sound banal, but having a bit of variation is good, and I was impressed with the options available.

The light sits well on most seatposts thanks to the three different straps included in the package. I used it on a mountain bike, a track bike and a road bike with no issue (I didn't use it on an aero post, though apparently it'll fit on one of those too). It stays in place well and firmly thanks to decent quality rubber and a thick metal buckle to keep it secure.

Operating the light is through one button behind the top of the unit. Holding it down turns it on or off, and a quick press changes the setting. It is simple to use and I found it easy to access the button even when reaching behind the saddle while on the bike. It's also highly waterproof – there was no issue whatsoever when using it in soaking conditions.

Claimed battery life ranges from 2.5 hours on steady high to 60 hours for eco flash. I left the light on in the steady low setting (5.8hrs claimed run time) at the start of the working day and it ran solidly until about 4pm; I didn't leave it on for 3.5 days, but used it on the eco flash mode throughout the review without needing to charge it, so I can believe the claim.

Charging is done through the built-in USB connector, which sits behind the buckle on the strap. It is simple to plug into the wall or laptop, although given the exposed nature of the USB it's worth wiping it off first. Charging takes 3-4 hours, so just sticking it in the laptop at the start of the day means it is fully charged by lunch.

At 42g (claimed 41g) it is unlikely to weigh you down, and its RRP of £34.99 strikes me as about right for a good quality USB light.

Overall, I was really impressed with this light. It is very well made with strong straps, a decent buckle and well-thought-out sequencing. The light pumped out is impressive and I'd say the battery life is as much as anyone is likely to need.

Verdict

A well-made, bright and well-designed light
