Here is what's new with MKIII:

• Reverse clicky switch is back
• Thinner tailcap allows more room for your finger, making the button easier to operate
  
• Better fitting CNC machined pocket clip has almost no gap between the body and the clip, and tailstanding is improved (smooth body still has a small gap since it's slimmer than frag).
• Anodized titanium screws
• New titanium washer with a keyring loop. comes with a split ring (if you need plain washer without the loop, see the link below description)
• Bigger inner diameter to support 10440 USB-C batteries

Compact size together with a proper pocket clip makes it effortless to carry around. Click switch with a simple UI makes it easy to use in different situations. Quality build and good materials ensure longevity, and all this without breaking the bank.

The light source is a Nichia 519a R9080 4000K LED. The light ships with a 350mAh rechargeable 10440 battery.
