So the new craze is to mod your reo to address voltage drop. Most people wouldn't even notice the difference. The thing is, most people shouldn't be altering their devices. If you have a background in electronics and you're aware of the risks, that’s another story. Removing the spring and replacing it with a loose fuse is a bad idea. There is room for something to go wrong and it will for someone. Someone is going to have a melt down doing this, I know it for a fact. Without the spring the battery can't drop and break the connection if there is a short. My first priority is safety.
I am working on a kit for sub ohm vapers that will reduce the voltage drop safely. I will push this as hard as I can to get it done quickly.
Please note that modifying your Reo nullifies the warranty. That doesn't mean I won't make repairs in the event of a problem, it just means you will be charged for the repairs.
