Happy with my purchase
superb
fast shipping and good quality
Happy with the purchase, reads my air rifles fine. Assembly is simple, just match up the logos on the light bars with the ones in the manual. The blue leds will light up when turned on if you have it right. To change from M/s to Fps, just push the button immediately after it says 'on'. It does not seem to remember the setting though and reverts to M/s after powering off.
Arrived well packaged, but a rag of instructions at least in English they could do (well that is relatively simple but with a little effort of translation...
The tool works very well. Manual is just chinese. To assemble well, you have to have a very detailed look at the pictures of the manual or search for an english manual in the internet.
Using it for arrow speed measurement. Works well, 3rd (spare) light row included, not too hard to get it running with a chinese manual :) (Hints: Battery containment is on the bottom. Press the only available button *directly* after initialization to change units. That's all.)
I used it to measure the arrow speed of archery. I could use it properly. Convenient
Manual in Chinese otherwise it is everything you could want for that price. Super fast shipping.
LIKE VERY GOOD
