I'm not convinced these Alzheimer's wander management solutions really work. There are now a bunch of these cheap iPhone apps that seem like they may work better even though they are more designed for kids than seniors or Alzheimer's patients: http://business.time.com/2012/09/14/should-you-use-your-smartphone-to-track-your-kids/
My experience with The Scooter Store left something to be desired. I called for help with getting a scooter for my husband and didn't find the operator on the phone to be very helpful. I feel like ordering these expensive products online is too much of a risk. I'd rather go to a local mobility store where if I have a problem I can go back to the store and get it fixed.
