DigiBall is a quite interesting product. I'll keep the description brief as I'm guessing most know about what it is and what it does. It's an electronic cueball that reports where you hit the cueball, as well as the speed and spin generated.
The components are all quality. The ball itself is Aramith resin and it feels absolutely balanced. I messed around with soft rolling it and watching for anything odd and I saw nothing that would lead me to believe it was off. It feels like a quality cueball and it reacts like one. It is one... a real quality cueball. The Charging Cradle feels solidly made and finished well. The included cables are of sufficient length. It seems silly to include this but nowadays if you buy a toaster the cord might not even reach the outlet. Pool tables can often be in odd locations where outlets are scarce. It's a small but usefull aspect.
The aluminum phone stand has a quality finish. It holds your phone well and is balanced. You don't have to worry about the device scratching anything, no rough edges and it has rubber feet.
The case that holds the ball should provide plenty of protection. All in all it seems like a well made and well thought out kit. The one minor nitpick is that if you wanted to take this with you you might need to get a small bag to carry cords in. Not a big deal and if the box that the kit was shipped in comes with the final product it is/would be sufficient to transport the cords. That and the fact the ball holds a charge for 16 hours you probably don't need to take the cords along to wherever you are playing anyway.
The phone app worked well "out of the box" and I didn't have to mess with anything on that end. The DigiCast pretty much just worked too. The DigiCast kit seems well built and is as easy to hook up as plugging an HDMI cable into your TV and plugging it's power cord in. My only issue was that I couldn't really find documentation online about it so for the course of the trial period it displayed my cueball speed in km/h. Not a big deal and I'd imagine if I had reached out this could be solved easily. I'm not entirely up to speed on devices such as this, but it seemed like it might be something similar to a raspberry pi. I don't know how the final approach to this will look, but something like a website or app for a computer where you could customize it would be nice. I'm guessing there may be something like this where you can update the firmware and settings. Again, I didn't reach out about it because I figured I could live with km/h for the trial period and my phone showed mph anyway.
The DigiCast is really cool though. We enjoyed watching it while in the spectator chairs waiting for next game. While playing it was easy to look up and see what went right or wrong after a shot. It made it really easy to confirm our suspicions, things like I decelerated/hit it too soft/threw the ball offline because of too much spin, etc. It's a cool thing to display and I could see it being a spectator favorite when watching the finals in a tournament or something similar. Kind of like a TV table where you can see how the ball was struck. You could even have a monitor on top of the light for spectators. You could do a really cool setup with this if you owned a room.
If you've played for a decent lenght of time you probably realize what you did wrong upon a miss. Seeing it on the screen and confirming what actually happened is usefull. It could be a distraction in a game situation if you get too deep into evaluation mode, but it's great for training and for the spectators. Subtle differences are easy to see, and often it's the subtle things that can go under the radar. Even the act of simply confirming your suspicion is powerful in practice. It's easy to forget about when you were first learning the game. This would be a powerful tool when starting out, trying drills, discovering what spin did etc. Another tool to analyze what does what.
I didn't use the streaming overlay because I don't have a setup to stream or record matches, however I could see this being great for live streaming or playback in general. Having accurate CB data while streaming is really neat. It's great for the spectators and for people to understand how a shot works. If I did livestreaming in almost any capacity I would use this. I can't really comment/review this aspect of the DigiBall but it's definitely a strong use case. I think the audience would really appreciate this when watching streams or tuturial type content.
Over the course of the evaluation I tried several things. We played a bunch of 9B. The built in shot clock was a neat feature. I worked for a couple minutes on my 9B break and that helped a lot for putting 2 and 2 together with results on the table. You could readily relate what the difference in 1/16" of tip position did when breaking. We even confirmed how not being stable and "jumping up" lead to a higher hit on the CB. Again a lot of this can be obvious once you've hit enough shots, but it's really useful for fine tuning and confirming your suspicions. You know for a fact where you hit it when you see it on the display. For example, on a 9B break, you can move the CB on the table across the headstring and see what that does when you hit it with the same speed and spin. I didn't focus heavily on breaking but I could see this being a very powerful tool if used in practice. You should be able to really fine tune things. Look for more break formats to become broken in the future!
I worked on the wagon wheel drill and that was very useful to see just how you hit it. Tip position registered accurately and you can really see how a good stroke contributes to the desired outcome on a drill. Not just tip location accuracy but you can see stroke quality too.
All in all we enjoyed the experience. I think DigiBall will be an excellent product for instructors, streamers, and students of the game. It's easy to set up and use. The trial period was enough to get a general idea but I think if one owned a DigiBall, you could really put the reps in, fine tune the app, track metrics over time and such. It seems to be a great training tool and I could see it working really well with student drills and/or a projection system. Let's face it, if you're an instructor and a rival instructor gets one of these before you do look out!

There are different teaching and learning styles, but if you can harness the power of data driven instruction/coaching it could be a huge boon, both for the financials and your student's progress. It also has the "wow factor" that students would appreciate. I can only start to imagine how well this could work with spreadsheets and for the data crunchers. Real analytical driven results like in other sports... think golf swing coaching. This product could lead to some real inovations and stronger competition in the future.
I kind of glossed over this aspect as it works so seamlessly you kind of forget about it, but just how damn cool is it that a cueball can do this type of stuff? I'd like to think of myself as a semi smart guy but I can't even imagine what went into the R&D on the DigiBall. The math would make my head hurt! I mean think about this... a real cueball that plays like a real cue ball should, is balanced, and has all this tech baked into the design! Imagine what guys like Dr. Dave, Bob Jewett, etc would/could do with one of these! Imagine what is waiting to be discovered...
It's a pretty cool and useful product if you ask me.
Thanks for the opportunity to give it a whirl!
