This is with a lighter and stronger aircraft grade aluminum. Comes in a nice cloth lined box. It is rechargeable and states it can hold a charge for 2 months. This is something that hopefully never needs to be used so you need to make sure you remember to keep it charge , just in case. The cable is included and it plugs in to the back of the flashlight. There is a red light that comes on when charging and the manual states never to charge for more than 8 hrs. or it voids the warranty It has a safety feature that allows you to use the flashlight without accidently discharging the stun feature. .The light has 3 settings, from a very bright 380 lumens to a strobe that you can use to signal for help since it can signal up to a mile. I also had a client that could not get out of bed and he taught me to flash the strobe in the person’s eyes if coming at you ..it really blinds you and they will not be able to get to you. Just like any defense weapon this should be kept out of a child’s reach and taught that this is not a toy! I have never used the stun portion on a person ( and I hope I will never have to) but I have tested it and it make such a loud noise that it would be enough to scare someone away. I received this product at a discount. All my reviews are based on my own experience and evaluation of the product so that others can benefit in finding quality products that meet their needs & expectations.
