This is an extremely good vertical grip as it works wonderfully with a Surefire G2 flashlight. The only downfall I see to this item is the constant on does not work on the one I purchased. Every time I attempt to set this to constant on by pushing the light switch up to lock it on the switch slides back down and will only allow for temporary on. Other than the constant on issue, fantastic item.
