Reasonably priced and seems easy to use? Sounds great.
Though I wonder how long it is before thieves find wire of the right size to make a tool of their own (or just buy a Drop-Lock to obtain one) to remove it. At least I assume removal is with some kind of wire tool through the hole in the middle of the device, to give you the necessary leverage to slide it out. If there was an explanation of how you remove the locks, I missed it.
If you contact them asking how its removed, they say you have to order it and instructions are provided on how to remove it. That leads me to assume there is no special tool to unlock this and all you need is a butter knife or credit card to do so.
I think the best deterrent is putting two baby seats in the back. I dont have kids yet, but I guess buying 2 baby seats is better than paying $250+ deductible and waiting weeks.
