I've never tried one but I'm also on the lookout for a no-escape harness since Taggart figured out how to get out of the one he has, so for months now it's there haven't been any walks with a flexi leash but just the regular short leash.

I really like the look of the Walkeez so if you do buy one, and find it's escape proof, please let me know. I took a look at the Rope N Go you mentioned too but that wouldn't work for us very well since I also want the harness to be used when we go bike riding.
