The M20 R5 is at the end of it\'s manufacturing life, being slowly upgraded by more powerful Olight models. Due to this, you can find it on sale for at an extremely attractive price if you do some looking. Other reviewers have covered it\'s features quite well and in detail, so all I\'ll say is that it\'s at the top of the class in regards to build quality and reliability. Given that this is not Olight\'s best, most expensive flashlight, and given the quality of this model - a second-level so to speak - I would have no hesitations of buying ANY of Olight\'s products. It is obvious that they take a great deal of pride in their products and their manufacturing ability.

This is a fantastic light- the fit and finish are perfect, and the ergonomics suit me perfect as well. The anodizing is flawless, and the throw is great. It\'s got a nice \"feel\" to it (with the ring attached) that I could almost fall asleep holding it in my hand and not drop it. I use mine with the Ultrafire 18650 3000mah rechargeable lithium battery (also sold here) and they work great together. Highly recommended!

I received this flashlight very fast, within 3 days. I\'d have to say the packaging was quite small and very well done (well laid out). Everything came undamaged.

Batteries:
1) It accepts the listed batteries and works with all types of 123A batteries (3.0V - 3.7V).
2) It works with the 18650 batteries.

Other information on batteries:
1) It may not work with some protected RCR123A batteries since it might not fit in the battery magazine.
2) It does work well with the protected 18650 batteries (I am currently use the protected 3000mAh UltraFire 18650 batteries).
3) Run time varies on mAh of battery, but the manual states about 4 hours of run time using 2400 mAh 18650 batteries.

Using the flashlight:
1) The flashlight feels very solid and well built!
2) The beam is very tight. I\'d say this light is more of a thrower than a flood.
3) You can buy a diffuser to make the beam wider.
4) I purchased the smooth reflector for this light and it helps the beam go much further.
5) The threads are well built and look like they\'ll last a long time, and each connection contains 2 O-rings.
6) To change modes, you slightly twist the head of the flashlight.
7) This flashlight cannot tail-stand unfortunately.
8) The head of the flash gets very hot after awhile, but the tube remains fairly cool. (About 30 minutes of use)
9) The light is smaller than you think, and it is very bright!
10) The levels of brightness aren\'t too noticeable distinct.
11) The striking bezels are removable, and so it the clip.
12) The instructions are clear and decent.

When I received the M20 Warrior Premium, the first thing I noticed was that the OD color looked more akin to a bronze/tan color, but it did look unique and kinda cool, and I\'ve taken a liking to it. The light output on this unit is amazing. With the orange peel reflector it is blindingly bright, but peak performance is achieved with the addition of the optional smooth reflector. I compared the M20 Premium with the Surefire Executive, Surefire 6P Zenon, Surefire G2(80 Lumens), Streamlight Polytac LED(120 lm), Condor CTC 112(160 lm), and even a Surefire L2 Lumamax LED(200 lm and nearly $200). This light crushed them all. The obvious contender in the batch was the Lumamax, but even that one couldn\'t compare. Very tight center beam and good surrounding circle. With the smooth reflector, most of the light remains in the tight center beam. Construction looks good and cutting edge brightness. Packed with all the latest features including a blinding strobe. What more could a guy want?

Good Torch... Par with the TK11 R2 overall. With both torches equipped with smooth reflectors the M20 had more shadowing and artifacts than the TK11. The M20 with the OP reflector had less shadows and artifacts and was about par with the TK 11 for pattern and brightness in its highest illumination level but the TK 11 had a farther throw with its smooth reflector. I like the M20 SS crenellated bezel and its low mode power saving setting and mode switch. I was able to leave it on strobe mode and have instant access to strobe mode.. My M20 was the OD model and I did notice some color variation with the adonization although I don\'t thnk it compromises the wear factor. I wish it came with a good wrist lanyard instead neck one. Otherwise, solid tac torch.
