Just thought I'd relate my experience with the Bulletproof synthetic green/hard tip.
TLDR; is it's a good tip, easy to install and it holds chalk unbelievably well. If you want a tip that lasts or have qualms about pigskin or animal products you could not get a better tip. It's also a good one for folks who don't care either way. They look really nice when installed, great shine with no effort. Just cut with a sharp knife and they are perfectly shiny on the sides.
I always face my tips on flat 600 grit emery paper before installing. It doesn't matter be it leather, phenolic, Kaumui clear (which says not to but are concave on the bottom so could cause popping off if you don't) or any tip. Face your tips flat if you don't want popping. I noticed it did need some facing. But after I already did that I watched the install video and that's how they did it. Good deal so far. Glued with Gorilla Glue Gel CA. I didn't have an accelerator so I left it set for 20 minutes while I watched some Peri Open 9 Ball on YouTube. I used a Japanese Kiridashi knife to trim. If you don't know they are a single bevel knife and will cut exactly flush with your ferrule. Less opportunity for error than with a double edged utility knife. They sell a disposable for $10 or something. I bought one for about $30 that can be sharpened indefinitely and have been using it for a year now. I highly recommend these knives for tip work (and even things like shaving CA flush while filling dings). Anyway.... The Kiridashi did a wonderful job, the sides are like a mirror when cut with no imperfections. I used a Tweeten shaper to sand to shape. I only have one of those drill based Sharpshooter "lathe" things, not really a lathe, but for the price they are excellent for tip work and cleaning. Not precise enough for things like threading or installing ferrules, but they work great for tips. I had no issue installing the Bulletproof synthetic tips on my setup.
I roughed it a bit by twisting sandpaper on the top and then did the same with a Gator Grip style tool. I was actually very impressed with how well it held chalk. I don't see any need for tip picks with V10 chalk. Maybe other chalks would need it, but that Gator grip type tool works excellently on all tips, from soft leather to bakelite jump cues, phenolic, and all in between.
The tip has a kind of unique feel to it. It's hard to explain but it feels more uniform than leather, like the material isn't full of natural fibers with varying grain if that makes sense. As a hard tip it's not "glass shattering" like a phenolic, it's a playing tip. To be honest, I can't tell you about the sound very well as I put it on one of my shafts that doesn't "sing" much. Some shafts resonate sound, this one does not with any tip so I can't attest to the sound, but it didn't sound pingy or anything. Just kind of a muted "thunk" if that makes sense. I like the pingy tips but this was not unpleasant and would probably be loved by those who don't like pings.
I broke with it about a dozen times and shot some shots. It feels good and I'd imagine longevity will be very good with it, though time will tell, but I have no doubt it will last a very long time. There's no mushrooming at all and no flattening or anything. You can put spin on like the dickens without fear of miscue.
It's a good tip and it's worth the money.
I have two constructive criticisms for
@Bulletproof Billiards , you spelled ferrule "feral" or ferrel" in your video (cant remember which). It's not a huge thing but spelling errors does not inspire confidence in some potential customers. Not everyone cares, some care a lot. I don't care, but it kind of seems a bit backyard mechanic rather than high tech. You're selling high tech stuff so techies will notice speeling errors.

The other thing, when you face the bottom of the tip... my gosh are you ever using an aggressive grit. I mean, if speed is important sure, but there is no need for such deep grooves. Also no need to put rings in a ferrule or silencer pad. I'm sure you've had all types being in the tip business but this is an entire old wives tale. Maybe it has less failure for less than good tip installers, and I suppose this could be why you recommend it. I'm not an expert on it but it's not needed. Maybe it makes no difference and I imagine it saves a tiny bit of time. CA does best on perfectly flush and slightly matte surfaces. 600 grit or 400 grit is about perfect. It looked like you rubbed those across a sidewalk.

I'm sure it works but really this also doesn't inspire confidence for those who know. Heck I used to use a razor blade to score tips when I didn't know any better. Just make the surfaces flush and use a good fresh CA (gel is good for DIY as it's less messy and has decent working time, less stuck fingers and glue runs).
I think you have a very good product here. There is a market for it and even if one doesn't mind using animal or pig it's still a very nice tip and I'm sure it will have great longevity. There isn't any detriment with it being synthetic vs. natural as far as I can tell. Great chalk retention and easy for tip installers.
