personally, I have/had 5 mods in 2 years. I started with a Joye Ego mod. It was great for my lack of experience. I highly recommend a spare battery and a charger if you go the route, as it takes forever to charge the 185650 batteries. for that matter always get an extra battery no matter what mod you are using. (Side note the Ego Mod does not like salt water). I then switched to the VAMO v2. This could be considered a lethal weapon in most states. It is extremely heavy and eats protank bases for breakfast (if dropped better have a spare base). My other problem with the vamo was the buttons were easy to push and no way of locking them. I burned out 3 wicks in one day because of this. I then moved on to the eVic. This mod does it all but costs a fortune. I still use this one, I just wanted more, so yesterday I bought 2 more. Nothing wrong with the Evic (other than the battery tube has worn off its finish), and I will probably use this one until i kill it. Now I have a Tesla, which I like so far (just avoid the protanks with it), It has a lock feature, and the buttons do not seem to be that easy to hit, so so far it passes the test. I also bought a mechanical mod called a ss-101 (at least at my local shop) I have seen it on other websites and they too call it a 101 just other letters added in. This is a no frills way of firing your carto. It works great for me and exceeded my expectations. I bought it for a utilitarian battery, but it may be my go to for a while (plus the $13 price tag without battery means it did not break the bank). Hope this helps!!!
