I can honestly say, I've never seen one before until now! What's the point of it if you can't see how the balls spred? Enlighten me please,
The purpose of the break rak is to practice hitting the front ball accurately. If you can't be accurate on your break shot, then how the balls spread becomes irrelevant, since you won't be able to repeat it. Here is what the Break Rak offers:
1) The ability to hit a bunch of breaks in a short time since you don't have to spend time racking. This can help build muscle memory.
2) The ability to practice your accuracy. The ball you need to care about the most on the break is the cue ball. You get to see exactly where that one goes.
3) The ability to practice your power. Get the break speed app, and hit the thing a million times. You can figure out how to hit harder, faster than wasting time racking.
Trust me...you learn how to pop that Break Rak good, and then go to a regular rack of balls, and all questions about its value will become clear.
Hope this helps,
