@fernand welcome back to the Solo family. The Solo 2 is my “go to” vaporizing portable for me as well. It’s easy to use wether you are curled up on the couch or vaporizing on the go while camping. The battery is long lasting and charges up in 3-4 hours when almost out of juice.
Mine works as well as when I bought it.
Not using a screen works best for me but you will have to decide the screen thing for yourself. I’m wishing
@ataxian buys one of these so we can hear his thoughts about the upgrades. Look for sales and take the plunge. Don’t buy one of these off EBay there are Chinese knock offs out there.
