I have the Revel (LOVE IT!) and I really prefer the Mios. The all-in-one design makes them great for traveling and just carrying around. They are super easy to use and I've had no significant issues with them staying in or getting the canulas kinked (I've only had a couple of "site failure" in the year that I've been using them). I like to always have extra infusion sets with me, and having everything in one little compartment makes life so much easier.
I am very active and sweat and shower a lot. Therefore, I do use the IV3000 films over my site. Medtronic now makes these with a special cut-out just for the infusion sites. THEY ARE AWESOME!! I have yet to have a site fall out when using the IV3000. Between that and the SkinTac, my sites are still quite difficult to pull off even on day 4 or 5.
