I have several gun safes and one of those Amazon special biometric safes too. But when I was going on a camping road trip with my family out in Northern-Western Montana I decided to buy a 10MM Glock on the rare chance we encounter an aggressive bear (and the bear spray didn't work). However, this posed a problem as I would need quick access to my firearm but not give any access to my 8-year-old or 4-year-old sons. The Idenilock was the near-perfect solution. I installed a magnet holder in my truck and one in the camper to keep the gun at the ready and it gave me peace of mind that my children would not be able to access the trigger. I've had the Idenilock now for nearly a year, it's worked flawlessly, and I'm now going to get a 2nd for my Glock 17. Now I said it was almost perfect and here is why. I would like to see a K-lock slot on the Idenilock. As it stands someone could easily walk off with the gun and Idenilock but if I was able to attach it to a short cable and the cable fixed to the wall or behind my truck's dash it would be a different story. Also, the Idenilock makes it difficult to use a rail-mount light. I was able to just barely fit an Olight Balor S on it but you have to move the light mount to its most forward position and it becomes well out of range of your index finger to turn it on/off. The convenience and speed of the Idenilock way outweighs these detractors though so I'm keeping it a 5-star review.
