I hadn't heard of the MaxiTPMS PAD, but I am of the same opinion as Top_Fuel. This device may be useful for a tire shop, but for the average Joe a tool like the TS-408 seems like a better investment. I see no reason to own both.

Being able to read your present sensors and cloning them is all that I would ever be interested in. Even if I was helping out a friend, I would want to be able to read their old sensor before cloning them a new one. Obviously, an old sensor could be removed & read that way, too.

I like the fact that the Autel MX Sensors are dual frequency (315mhz and 433mhz), & approximately $30 for rubber or metal stem sensor doesn't seem like a bad price.
