I love the idea of tracking technology and the beeping feature making it easy to find discs when you're playing those long grass courses. For me, there is nothing more frustrating when playing disc golf than spending time looking for discs, especially on good throws! To me it's well worth it to pay more for a disc that will ultimately save you hours of searching in the long run. The way the tobu works, is that as long as the USB battery is charged, you can "activate" the GPS and beeper by the mobile app any time you need help finding the disc. It gives you an approximate distance the disc is from you, and as long as you're within about 70 feet you can usually hear the beep. I tried the original Tobu Charge, but didn't really like the flight of that disc and so was excited to try a more understable disc with a tracking module.

I'm a low snap backhand thrower who plays at 4,500 feet elevation. My primary drivers are Tournament plastic Westside Hatchets and Kings.

With the name "Power Roller" I was expecting this disc to be really understable. My first throw with it was on a straight shot that cannot fade too early or else it misses a mando about 270 feet out. The Power roller faded out immediately on me (low speed fade, not high speed flippy turnover) and faded out so hard at about 240 feet that I wasn't even close to the mando tree. Looked like a throw from a beginner.

Realizing that the Tobu Power Roller isn't nearly as understable for me as the discs I usually use, I treated it as an overstable disc the next throw, and it successfully didn't turn over and faded hard past the basket and out of bounds.

My next throw was on a long wide open hole. I went full power and got it to stand up and turn a little bit, but was still probably not even able to get it out to 300 feet. It probably has something to do with the tracking module, but this disc just doesn't glide a lot, and doesn't go as far as it seems like your throw tells it to go.

By this point I figured that the only way I could get adequate distance out of this disc is to use it as the name suggests - a power roller. My first few holes I tried backhand rollers. I failed miserably and couldn't get enough on it to make them roll. I was convinced that this disc really is stable and that the only way I could roll it was forehand, which worked great! After figuring out the angle I needed to release it at, I was able to get about 400 foot roller out of this disc. It was one of my best drives ever on one particular 600 foot hole.  When the Power Roller rolls, it doesn't behave like an ultra understable discs. It stands up and stays straight for a while and some of my rolls ended up on the overstable side.

If you're looking for a disc for a great flight and more distance, then the Power Roller is not the disc to get. But if you play courses with lots of shrubbery and long grass, I highly recommend the Power roller for the convenience it will provide by not having to spend hours looking for lost discs.

The Tobu Power Roller is a disc with onboard electronics that syncs with your iPhone or Android via Bluetooth.  That is a very handy feature if you fear losing the disc and want to locate it with ease. That also amounts to a much more expensive disc than usual. 

If you plan to spend that much money on a disc that can be easily found after the most errant of throws, then you probably want to know if it is a disc worth throwing. Thus, my review is not on the electronics, but on the disc itself. I am an intermediate player that throws backhand, and when I give the Power Roller a good throw, it definitely pulls to the understable side. I have to dial my power back to get it to fly straight. But that means that this disc is designed wonderfully for new players without a lot of arm speed. It flies quite a bit like a Sidewinder or a Sail, giving new players the advantage of a driver that "fights the fade" and gives them more distance. When thrown with power, it lives up to its name and flips over and rolls, exactly as advertised. So, if you throw hard, the disc is going to hit the ground and roll. If you play with less power, then the disc will be a nice one for you. It can also be used for anhyzer turns when thrown higher. 

I found the disc serviceable, though not necessarily one that matches my playing style at this point. I can tell that it was designed for new players, giving them a disc that is both easy to control, and easy to find when control is lost. Four stars for a disc that fills that "new player" niche!
