Our sample unit shipped with a nice accessory package that included the holster, safety documentation, manual, clip, safety glasses, lens cleaning cloth, battery, charger and a clip.
The first battery and charger ship with the stock package, but you can purchase extras from Wicked Lasers.
The holster is an add-on, but it includes a belt clip and does a good job of securing the laser.
Our last extended lens kit didn't have the identification stickers and it made it difficult to distinguish one lens from the other. Wicked Lasers has really improved upon the kit by including the stickers that tell you what lens gives which effect.
The Arctic ships with orange lens to offset the blue light, but the Krypton ships with a deep red lens. It is very important to remember to use these especially if you are in an enclosed space like in the house. With this much power even dark colored items reflect a surprising amount of light and you can easily suffer temporary damage to your eyes. With the Arctic on a few occasions we walked around seeing a blue dot for up to 30 minutes when using the laser without glasses on. The Krypton seems to be easier on the eyes even though it appears much brighter.
