Never had problems reading monitor with the TT500. I do like the support and Lifetime warrantee that you don't get with the EZ. That's why I bought the TT500. Did you read mycouple of posts on comparison of TPMS? I didn't do the EZ but bet most of the comments still apply.
Roger, I know from your blog that you have and favor Tire Traker TT5500. I have narrowed my shopping list to either the TT-5500 or the Eez Tire. It appears from the various reviews that these have similar characteristics (warranty not included) except that the TT display is portrait orientation while the EEZ is landscape. The landscape orientation appears to give the EEZ a larger font display, which to me is a plus. What am I missing? Truly value your opinion.
