Since I prefer detailed reviews, I try sometimes to such. As has already been said, bike mount is just as simple, as yet functional. Both ends are made of elastic rubber and two different sizes, so you, for each lamp handlebar combinations, a lot has room for maneuver. Let us have noticed me now to things. Due to the fact that the holders are very elastic, the Lampbe wobbles with unpaved or rough road conditions. So if you use a lamp that has a very focused hard transition, and does not generate defuses evenly distributed light that can be very uncomfortable. I had a "Olight OL-M20WS Warrior Special Operation" as a test lamp. Since this has a very hard transition (without Defusor) which was a bit annoying. I have to a powder-coated downhill handlebar on which the construction has unfortunately less maintenance than expected / desired. I have tested them sometimes on a smooth aluminum handlebar of my two trades, where they hold better. The grip is unfortunately dependent on the respective lamp. You should align the lamp so that the focus is located on the handlebar, even if sometimes not be the cheapest fixed point. Then the displacement, vibration, remains limited. But if you want lock a strong head or neck-heavy lamp, this solution is not suitable because the lamp can therefore not be clamped in the middle, and therefore too far in the above is a direction or another. In my case, the cold was possibly also a problem as it was to test drive around the 0 ° C and thus maybe something had to lose flexibility and thus the static friction rubber.
on the whole, I find the price-performance ratio still good. If you play a kind, considered one or the other mentioned issue, and now and then a little after, then it works properly. I gebackt something silicone to the Velcro (insides), whereby the stop for my combination turned out really well.
