I like the Sense-ible (or Sense-ation... same company, slightly different harnesses, but not much) better than the Easy-walk. I have both, but hardly ever use the Easy-walk (we bought it on vacation when Kodi chewed through is Sense-ible harness left within his reach in the back seat!
I find the straps and buckles on the Easy-walk a pain in the neck. The straps tend to slide through the adjustment points, so you have to readjust them often to maintain a good fit. The buckles are also tiny and fussy to open and close on a long haired dog.
I replaced the Easy-walk with another Sense-ible harness as soon as we got home, and now it just hangs on a hook as a spare"!
