“Very great product. Using to quit vaping. Was hoping more more resistance to simulate drag more but overall good quality and useful. Would recommend but with some caution to smokers. Be ready for an adjustment. Well worth the work and breathing practice but an adjustment for sure. Good luck and breath easy.”
“Not keen on the ball chain which is why I got the big chain, just in case. It's a matter of personal preference, chain is good, just not my preference.”
