You have to get used to running with such low pressures as you do with this. Ive run as low as 7 lbs - great traction but a little squirrly on the road. I kept thinking I had a flat.
One real bonus with this system is the ability to continue to drive the bike on a flat without ruining the tire or the rim. I was out the other day and was a few miles back in the woods and had a sharp rock pierce my tire. I had a flat. I was alone with full gear on and it was about 32 C(90 F). I really did not want to get into fixing this on the trail. I fired up the bike, sat up on the seat a bit and rode out in second and third gear and even did a mile or two of pavement. Stopped in at a Buddy's place to let him see the results. No damage to either the tire or rim. In a straight line you can barely tell you are running flat - you can still wheelie on it - I tried.
I had forgot to put slime in the tire before that ride. That may have kept me from having a flat in the first place - so they say.
I brought the bike home, pulled the wheel off, pulled the tire off, pulled the TuBliss off (just to check it out), and put a plug in the tire. Reinstalled everything and aired up. Plug holding air just fine and then added SLIME for the next flat event.
Rode the bike for about 3-4 hours last Saturday with no issues with the plugged tire still running at 8-10 lbs.
CONCLUSION - the TuBliss can pay for itself the first time you ride the bike out of the woods on a flat without ruining your tire or rim. I think it is a great safety feature in that regard too. Fast too - if I had my plug kit with me, I could have fixed the hole in about 1 minute and aired up and been on my way - Awesome, much better than patching a tube. I think I will get one for the front next year.
