I had the altec show and go installed a couple weeks ago.
Got railed with 6 tickets within a week parking at my gfs apt. So decided to put that on. lol
FWIW the plate holder is made by one company (Altec) they hold the patent. So you may find them with different names, but its all the same shit. Get whatever one you can find the cheapest. I got the electric one btw. You can get a manual one if you like.
