My daughter and I really enjoy our Evod setups. They are very easy to use and maintain, replacements are relatively inexpensive. We have had to replace tanks and batteries a few times, and nothing "breaks the bank" - we are on a relatively tight budget, so ease of replacement and low cost are concerns for any equipment that we purchase. The main expense will be coils, and those are relatively inexpensive. The coils can also be cleaned and reused several times, and, if you are so inclined, can be rewicked and rebuilt to further prolong their usefulness.
If you decide to go with Evod kits, please be aware that the tanks are plastic, and not for use with certain eliquids known to damage plastic tanks, known as "tank crackers" such as cinnamon, citrus, etc. Some eliquid vendors list which of their eliquids have been known to damage plastic tanks, and there is a list somewhere here on ECF. If you can, you may want to order a glass tank or two at the same time you get your kits. The Protank 2 Mini works well with the Evod batteries, and takes the same Kanger single coils as the original Evod tanks.
If you decide to go with Evod 2 setups, those tanks use Kanger dual coils, and the tanks that come with the kits are also plastic. We are currently using Evod Glass, which take the same dual coils as the Evod 2 plastic tanks, and are very happy with them.
Mind you, my daughter and I quit smoking, cold turkey, around 9 years ago. The cravings never left us. Around 3 years ago, between stress and cravings, we were just about ready to cave and get some cigarettes. My daughter had heard about ecigarettes, and we did some research, and finally got some disposable Blus, just to see if vaping would work for us. We have not looked back. We switched from cigalikes to Evods almost 2 years ago, and are very proud and happy to continue to be ex-smokers.
We have found Evods to be reliable, and they provide a good vaping experience for us. They are reasonably priced, and will help you to decide if vaping is right for you.
