Most helpful critical review
Having gone through a few of these...
on 23 November 2014
I'm on at least my third front and second rear one of these in the course of about 5 years, due to a combination of theft and on one occasion, collision damage. Obviously I liked them enough to overlook a few issues and buy again, but at the same time I hoped the manufacturers might have addressed a couple of issues in the intervening time. I think these lights have a lot going for them, but have had similar problems now with successive lights, and will be opting for an alternative next time.
- Very simple to fit and remove.
- No need to fit a holder/clip, so less clutter. No prospect of the clip breaking and rendering a perfectly good light useless. Also very easy to relocate or even swap to a different bike altogether if desired.
- Using rechargeable batteries in both lights.
- Very easy to adjust the angle of the front light when riding, for whatever reason, e.g. for changes in light, terrain, road conditions or just personal preference.
- At the same time the lights grip solidly and don't move unless intentionally moved.
- Strong rubber casing survives countless fittings, removals and battery changes with no issues at all.
Cons - quality of electronics:
- The button on my current front light has become very temperamental - on/off is absolutely fine, but it is now almost impossible to make it switch to solid beam when required. It also seems to have become hyper-sensitive (same problem I think), so a bump easily puts it back into flashing mode again. This is annoying and potentially dangerous if it were to happen at the wrong time. The buttons in particular seem to be a weak point on these and also the smaller Frog lights (I bought one of these once as well).
- On my old rear light, the outer LEDs (or that part of the circuit) died, leaving only the brighter central one. However it remained adequate for my purposes.
- One of my old front lights lost its water resistance and decided to go into low-battery strobe mode whenever exposed to rain or snow.
Cons - design:
- Dazzling glare from the top of the front light. I solved this with a bit of black electrical tape - another reviewer had the same idea.
- While they are simple to fit, as others have mentioned they can be fiddly, especially in cold or wet weather. It pays to make sure the rubber strap is properly hooked on and secured by pressing down on what is actually a very small area - not always easy with gloves on, or frozen hands.
Battery indicator (lack of instructions):
As others have mentioned, the red and white flashing on the front light is the low battery indicator. If ignored, it eventually goes into a strobe mode and refuses to switch off until you take the battery out. However as the instructions neglected to mention any of this, you could be forgiven for thinking it was a fault.
