Thrunite Catapult issues

Hi all.

I just have a question regarding the above light.

Bought the light locally a couple of years ago, but have had a few problems with it recently (discharges battery very fast, or just dies).

Is there anybody that I can take it to to have a look / give it a service?

I know the light is not particularly powerful (700 lumens) given the output of today's LEDs, but it is a nice sizeable flashlight with a nice throw due to the large reflector.

Any advice would be appreciated.

Thank you.
