Vero SE Series poke in connectivity.....

So for my first post, I feel the need to share what I just experienced......I've been lurking on these forums for weeks now, absorbing every bit of incredibly helpful information that all of you COB Led pioneers are so willing to share......I've literally spent hours upon hours reading, pouring over data sheets, watching videos ect, preparing for my first COB build.

The learning curve had given too much credit to the stability/durabiltity of the poke in connectivity. I chose the Vero SE specifically for that feature.......
16 gauge solid core wire seemed to fit nice and snug, in fact I had a difficult time removing the wire with the release. It is a possibility that I damaged this release during a removal, precisely why I'm sharing this right now.
Fortunately, expecting novice errors, I began this endeavor with Vero 13 and Vero 18 SE series COBs only, so no real financial penalty has been suffered. Here's what I discovered....

If you twist the COB enough, that poke in connector will release....I was testing temps on a small active heatsink and had to twist the positive lead out of the way, I had left a bunch of slack on my test lead, it was getting in my way, and as I bent it away, the COB flickered and blew out.....I noticed the wire I had poked in had come loose from the original position I had set it, I pulled what I thought was hard enough on that lead before I powered up....
After the COB blew, I experimented with the strength of that poke in connection, found that 3/4 of a rotation on the wire and it will slide right out without using the release.....
Possible the wire is too large for that connector to grab properly, or I damaged it at some point, but I just thought Id share what I just found out the hard way, those connections are not as stable as I imagined......

I found them a bit fiddly at first until I worked out that I was stripping too much of the wire. After that they were as solid as a rock using 18 gauge stranded wire. I think the strands probably help with the grip as well.

If the jacket is very thin it might fit, but 18g with 2.01mm jacket will barely fit. Keep an eye on the voltage rating of the jacket if you're wiring in series.

I did assume the failure had everything to due with human error, I was just a bit surprised how easily I was able to twist that COB right off the spring connection, once I began experimenting after the blow out. SO I definitely need to get the 18ga wire, evidently I neglected to read the specs closely enough or I would've found that 18ga is not supported.
At a minimum, I discovered I need to be far more careful in securing that connection.....
