I've been pretty happy with the carwashmsi dispensers I have for a wash select II at one wash. They've been in around six Months maybe. Customer response has been great. My biggest problem is the value is too good. My $8 wash gives a
token good for five minutes of vacuum, a $2 value, and the basic four pass istobal does such a good job that's all a regular washer needs. But with a tunnel coming a block away I'm hoping to maintain a good value for those that don't want to be members. I also offer a bug spray prep station and free drying towels.
I need to improve my signage though as about once a week I get a call about how to get a free vacuum when you wash.
