I've always used them too. At Walmart you almost have to because the line is ridiculous if you want an actual cashier. At most other places I haven't had much of an issue. The only thing I don't like is the glaring "do you have coupons, do you have a rewards coupon, are you SURE you don't have coupons? What's your phone number... yada yada" that it gives you. It's painfully annoying.

If they could silence these machines, I'd be happy, but I suppose you can't have it all. I agree with Guardian, I think they are much faster going in and out.
