Do either read both psi & temps?
Are the batteries in either user changeable?
Do you have mail in the sensors for battery replacement?
Does either have a monitor or can only be viewed on your phone?
Personally I want a monitor so as to see temps & psi at any time, just just when looking at the phone.
How's the reviews on those systems & their customer service?
These are few of the important things I looked for, so bought the TST507 as well. Possibly not the cheapest system, but met my needs.
