I wouldn't know and I'm not a fan of them but surely if switching to a disposable got someone off smoking that's better than them continuing to smoke.
This 100%. For me it had nothing to do with "can't be too bothered", every vaper i have met has personally asked me for a cigarette on multiple occasions. To me it wasn't something that was effective so there was no incentive to spend £50 getting all the equipment and research to try something that I had no confidence in. I only ever used 2 disposables to reduce my smoking and once it proved effective, I already had a device on its way.
They provide a cheap hassle free gateway to vaping that significantly reduced my smoking and can for many others.
