I've tried the Smoktech LR's...They're not bad. I bought 5 and they all metered out to +/- 0.1. The wick kept up with the coil, but they weren't the best at producing vapor. They also didn't last as long as a Joye LR... I hope it doesn't sound like I'm bashing the Smoktechs. I'm not. I'm just saying that there are better options for $5 attys IMO.
