Ive been with progressive for almost 10 years now. The last 2-3 years, my policy kept going up, and I couldn't figure out why. They said my next renewal I qualify for some deduction because Ive been a loyal customer for so long, well I never got it, and my policy went up again. Long story short, they gave me some bullshit answer to why my policy kept going up, yet the answers they gave me had nothing to do with me, but other drivers that have shitty records. Not to mention I moved from a nice location to a much nicer location, and my policy went up slightly again because I moved. Im about ready to renew, so Ill be calling them bitching again for my high policy.. Fuck, I insure 4 vehicles with them, you would think I would get something extra, mind you we have no accidents or tickets either..will see.
But to answer the snapshot question, I did this on my wifes vehicle and on mine, and I wound up getting a few hundred bucks back for both vehicles, or like 10-12% on each. The damn thing is sensitive as fuck. When you brake with it, if you don't slowly do it, it beeps. I guess from their feedback, hard breakers are more likely to get into accidents. I don't consider myself a hard breaker, nor is my wife, but its almost like your driving so you dont hear the damn thing beep. And if you have to suddenly break for some reason, like for an animal in the road, or someone in front of you breaks too soon, its going off. I couldn't wait to give the snapshot back. I think mine was longer then 30 days, I think I had mine for like 6months..
