Good Product

Has been on my truck, which sits outside in NH, for about a month. Has kept my battery from draining in these cold winter temps (sub-20 degree average) in-between days it gets started/driven. Would recommend if you just need something to pair well with your block heater to protect your battery from draining.

Yes, I recommend this product.
