Very high quality, strong light and good battery.
The problem it has is that when it clips onto the base, the center of gravity is too far forward and in the potholes and bumps (which our roads are full of both) it slips forward. If I tighten the base more, there is a risk of it breaking. Maybe it can be fixed with some wedge.

Evaluating the intensity and focus of the light as well as the battery life, it is quite good for the money. It has 4 levels of steady light and 4 levels of flashing light. On the 2nd level, which covers the needs of a classic narrow illuminated path, it lasts about 4 hours. The last level is enough to move in complete darkness (mountain) at low speed, but for a normal descent, additional lighting with greater focus may be needed.

In the positives, the light is very good, like a scooter. In a space with no light at all at night, you can see very well and at a satisfactory distance. The modes are convenient and easily changeable with the top button, so you can save battery when there is light on the road.
In the negatives, the strap has specific notches and on my handlebars (an Ideal Trial Mountain bike) it doesn't tighten well and gradually falls down. I will try putting something on the handlebars to give it a little more volume.
Only time will tell about its durability.

Maybe the review won't seem helpful because I use it for my little one's bike (4 years old) but the light is perfect. Good battery life.

Incredible flashlight...!! A little thing and it has such powerful light like a duck. The battery is endless, been using it almost daily for a week, around one hour per day and it still lasts. I recommend it with closed eyes.

Very powerful light and very sturdy construction. Highly recommended. The small one broke its base after falling twice and the light only has minor scratches. I bought the same one again.

I have tried it and even though it's raining and there is a little fog (because cycling as a philosophy is not only when it's sunny, it's a multitool...) It has user instructions. The plastic strap tightens enough to fit securely on any handlebar. It has 2 settings: one is the continuous light and with each press it goes forward (25% brightness, 50, 75, 100) and the other is the flashing at corresponding percentages. To change functions, no matter which setting you are in, simply press the button twice quickly and it changes. With lower light setting (50% is sufficient), the battery lasts longer. For the average user, with proper full charge-discharge, the flashlight lasts 4-5 hours. It's worth its money and the practicality-comfort it offers!

2 stars because the grip on the handlebars is very loose and constantly moves from its position due to vibrations. In terms of lighting, it is very good, after all, it is 700 lm. It is logical to illuminate strongly.
