I received this flashlight from Cigabuy’s giveaway. Priced $13.95 on their site.

The flashlight arrived in blister pack. It had cheap lanyard included (click on pictures to see full size image):

Construction:

The body build quality is good. No flaws is machining, no sharp edges, smooth threads.Good anodizing, I didn’t notice any flaws. The brand name is engraved on the body. The lens looks like glass, reflector has some minor flaws.
The head is glued. The head part is relatively long, almost half of the total length. You need to remember to hold the light further from the head compared to other twisties, but one hand operation is still easy.

Internals are not as good: The driver is a loose fit inside the head and the contact board looks sloppy:

The light starts to flicker about 10-20s on. Slight drop in light output for a fraction of second in about every second. Cooling the head with ice stops the flickering. I guess the driver overheats because of poor contact.

Light Output:
The flashlight is brighter than my Thrunite TiS (60lm). I would guess around 100 lm. The tint is pure cold white, colder than TiS but not blueish.
TiS - Left, M37 - Right (They both look white, my white balance was set to warmer light and made it look blueish)

The main beam is a little bit ringy, barely noticeable in real life use. Outside the spill there are few pronounced rings. They do noticeable but don’t bother much because they are outside of the main beam and dimmer than the spill. I think XP-E or OP reflector would help.

High/Med/Low:

There are 5 modes in the following order: Low>Med>High>Strobe>Sos. The light starts on last used mode. There is very little play in the threads and mode switching is reliable, without skipping. I would prefer less modes, 2 or 3, but with mode memory it’s not a big deal for me.
There is horrible PWM on lower modes, about the same as Solarstorm SC01.

Conclusion:
It’s a nice host, but glued head makes it harder to get to the internals. If I could fix the flickering issue it would be a nice flashlight. It’s possible that I’ve got a bad sample though.

Great review sir, and fotos as well. The blinky modes and PWM are a bummer, but it looks like a neat little light. Lets hope the flickering problem is just a localized problem, is it me or the hole for the emitter in the reflector is a bit too big? Thanks for the review!!!

Thanks for the review.

I have the Odepro version, which looks about the same. Very similar to Fenix LD01. I’m EDCing it now before I review it.
