excellent chrony but the batteries sux... mine blew on the first charge... so i puted 7.4V lipo in there with a PCB so it also can be charged from ordinary 8.5V ac to dc adaptor

Great product with the lowest shipping I've seen from HK and super quick.
A local club has the original Guarder one and I can't see any difference (same problems with dim LEDs - just tape a sunshade to it). Reads the same FPS as several other chronos I've tried.
Some specs:
- 2-500m/s range
- Joules based on 0.1g BB (seems weird... I just read m/s or FPS)
- internal battery lasts 4 hours
- 1.5 hours to charge
- M6 tripod screw
Overall it's cheap, solid and accurate.

Great deal compared to other models on other sites, with registered speed post very low shipping cost also.
The battery (300Mah NiMH 7.2V) in my unit came loose from the roof of the unit so I resecured it with some super glue and it is fine now.
If you are not in the EU make sure to but or make an adapter. All I had to do in the USA was solder/heatshrink standard prongs onto the European ones because the voltage and frequency was correct.
Overall it has the same minor problems as the Gaurder, such as a dim led display, but it still is a fantastic steal.
Thanks for the great products and prices RSOV!
