How many occasions are you referring to? Like hundreds of people every day, I've collected Sat Nav units from car rental companies in the US and never had the slightest problem even when I haven't pre-booked one.

I certainly agree that rental through this site is good value but you do have to rent the unit for the entire period of the holiday and if somebody feels they need that then I'd endorse your recommendation. However, I've found that I use it less and less as the holiday goes by and I get my bearings so it always seems to stay at home for the last few days while I'm still paying for it.
