I just took delivery of a Revolver X4"s". It's crap. They ruined it (old x2 and X4) with "new" cheesy, flimsy, plastic corners at the tailgate that you can pull off with a fingernail, leaving a 1" hole ,inches from the release cord. They will get knocked off constantly. Wussy plastic butterfly and wuss-pin. (Seriously! Zoom on that last pic and look at the design; you'll get a good laugh!). It's the lamest, worst, "upgrade" I have ever seen, "in LIFE!"; top-3 anyway. It's a BIG step backwards. I just ordered the Sentury CT to replace it, but despise the the notion of velcro all the same -- but there's your choices -- X4"s"hit, or velcro. I cant succumb to stupid, so I went with velcro.
The X4s, and "BAK" for that matter, is now dead to me --they're all incestuous in this space anyway, so I just made a horizontal swap within the same enterprise! Irony!
Massive waste of time. CS said they take calls "every day" for this problem and it's being "considered" for redesign. Buyer-beware "everywhere" these days!
