Excellent grip. I did notice that it leave chalk on the cue ball on hard shots like the break. Probalt because it is soft and paste on well.

Fine grind of chalk allows it to stick on cue tip better than most.

I laughed at this when I first saw it. Almost $30 for a piece of chalk? WHAT!!! I was wrong. This is a great product. Played 20+ racks with a group of 4 and the chalk looks like brand new after everyone using it--I imagine 1 piece will last 6 months (for someone that plays 50 or less racks a week). The other thing I noticed, besides the tip being perfectly chalked for shots, is that it doesn't dust out on your cue, table, clothing, etc... That really annoys me about most chalk--It gets on everything! Really good product. I'm still shocked that I bough a piece, but very glad I did after using it. No gimmicks on this product--works exceptionally well!

I bought this after looking at some youtube reviews on pool chalk and it tested right up there as some of thw grippiest and easiest to apply and longest lasting. Never thought Id spend so much on a hunk of chalk but damn even just feeling it on the hand... it is SMOOTH but also sticks, its fantastic on the cue, no regrets.

This chalk exceeded all expectations I have ever had on any pool cue chalk! I waited a while to buy this because a) the price point, b) a video I saw a YouTube video by Dr.DaveBilliard that had me concerned about the Kamui chalk producing more cling, and c) the color of this chalk is very different from the color of my table cloth which can be messy looking. I recently switched to a Predator carbon shaft and found that my bridge hand seems to be getting covered with chalk much faster than in the past, possibly because the carbon shaft does not hang on to any of the chalk residues. So they all end up on my hand. My table also seems to accumulate chalk much faster. I decided to try a cube of Kamui Roku Chalk. I have only played 6 racks with the new chalk, and it is so much better than I expected that I feel compelled to sit down and write this review. None of my 3 initial concerns was founded. I have only chalked 3 times in six racks! I waited until I miscued after my initial application, and it took 3 racks to happen. OK, this may not last as long as a gross (144) of regular cue chalk, but this one cube will last me a very long time. There is very little sign of chalk on my table, and very little sign of chalk on the cue ball, and no sign of chalk on my bridge hand. Cling has not been an issue especially if you clean your cue ball every now and then. And I bearly need to clean my table now after 6 racks. The cue ball also needs a lot less cleaning. I am guessing that this will extend the life of my Simonis cloth because it needs to be brushed/cleaned much less frequently. Most importantly, the chalk really clings well onto the cue ball through the stroke giving me much better control and reliable spin! I can't believe a little cube of chalk can make all these differences! Highly recommended!UPDATE:I have used this chalk every day now for a couple of weeks, and I feel compelled to write an update. I like this chalk... no, I love this chalk even more that I initially thought. First, I learn that unlike its predecessor, you are supposed to use this ROKU like a regular piece of chalk, as in apply often or before every shot. I find that applying every few shots, or before every shot on which I plan to use heavy English is sufficient. This chalk not only allows me to apply a lot more English on the ball, but it also keeps the ball much cleaner. I used to find a lot of chalk marks on the cue ball after every rack. With ROKU, the cue ball stays super clean. I just need to rub my hands on the ball a couple of times to get a completely clean cue ball. My table also stays a lot cleaner and requires cleaning a lot less frequently. When I do need to clean the Simonis cloth, I use the Simonis X-1 cloth cleaning tool that has a felt-like fabric on the bottom. I guess what makes this chalk clings much better to the cue tip and the cue ball also makes it cling much better on the X-1 cleaning felt. Just running over the cloth once gently picks up what little chalk marks there are on the table.My initial reaction when seeing this chalk was, "$30 of one piece of chalk?!!" Now I would buy this once a month if I have to. Luckily, this chalk seems to last forever even when applying frequently, so it will last me many months. My table cloth will certainly last longer because of less frequent and less harsh cleaning. On top of that, I learn that I can buy this chalk directly from Kamui for $25 with free shipping. This is a no-brainer. Try it!
