It seems mechanical mod has become a household word these days and everyone has one or plans on getting one, some for different reasons than others. There are some good ones and there are some bad ones and unfortunately a lot of people don't really know the difference or even what makes them different. Without getting to far in depth I can say the material used for contacts makes the biggest difference between great and not so great, and cost is often a factor in what materials are used. But as far as a good beginner mechanical mod i would have to go with either Kamry K100 or K101, which are virtually one in the same other than grip design. For more information on that I recommend you visit this Kamry article that provides more specific info. Kamry made a good decision in choosing the Empire mod as the inspiration for their mechanical flagship, the K100. On the surface one might say it is just a copy or knock off but those terms usually denote poor quality and cheap materials just to make a quick buck. That is not the case with the K100 and K101, which are made of quality materials, a solid durable build, attractive design and neutral colors for both males and females alike, is easy to operate, takes all 3 lengths of 18mm batteries, and is compatible with all 510 and most eGo attachments. Also, even though IMR Protected batteries are recommended, mine came with a magnetic short stop fuse made by Kamry as well. I don't know if that is true for all, but at least they do where I got mine. Sure there are a LOT of mechanicals out there to choose from with Sigelei, Beautiful/Riva, L-Rider, and so on but as far as the total package that requires nothing more than inserting a battery and picking a compatible atomizer, I have to go with the Kamry K100 and K101 as my choices to recommend as a first time mech mod.
