Yocan Uni S Review

Picking up the device for the first time – You’ll instantly notice that the Yocan Uni S has a really high quality feeling metallic chassis, made of zinc-alloy. The device is much smaller than the Yocan Uni, and Yocan Uni Pro (check the video below for size comparison between the 3 devices – you’ll see its way smaller!). It fits in your hand nicely and is really durable, yet nicely lightweight. The device just has a great premium feel to it!

Best 510 mod around. Super easy to use and great size for portability. Would purchase again

Perfect compact battery. Low setting works perfect for my main carts. Preheat funtion is handy for when it’s cold out and the oil is extra thick. Super compact design.
