I ordered both the free blue soft tip and 50% off green hard tip. I installed them both myself using a lathe and the techniques shown in their video using fresh Loctite Gel superglue. My finish was not perfect but looked pretty good and I was happy with the results, neither tip popped off so I'd say the glue is working.
The soft blue tip had a very nice feel and sound to it, however I felt I could not get my normal amount of draw on the cue ball when compared to other soft tips I have used. This was my only complaint, otherwise the tip held chalk great, felt and played very good.
The green hard tip plays much like other hard tips, I can get my normal amount of draw on the cue ball with it and all other shots perform like other hard tips. It hasn't not changed shape either and holds chalk very well. My biggest complaint for this tip is the noise it makes, but this is a completely personal feeling and does not affect play. I have the tip installed on a 12.5mm carbon shaft with T34 ferrule. I have a feeling on a wood shaft the noise would not be as loud and more tolerable to me.
If you are looking to try a new tip technology and aren't afraid of something different I say give them a try. They do exactly what the manufacturer claims they will. Just like everything else, they are not a silver bullet but they do perform as stated, you just have to decide if that is what you want.
I have a red medium on order that I am going to replace the soft tip with, I have a feeling it will be a happy middle ground for me with performance, feel and sound. I will post a review once I get it mounted and play some games with it.
