Can't remember the name of the vape I used because I have luckily managed to quit nicotine, but look for a vape that has refillable cartridges. That way you can buy a couple carts and whatever juice you want to refill them several times. Otherwise you have to fuck around with wicks and stuff, or have to spend a bunch of money on prefilled carts.

Juul is okay but the carts are very expensive and they don't have much juice in them. I have refilled juul pods before but it is challenging and messy.

I used to buy 30mL bottles of juice and refill a cart ~10 times before tossing it since the wick will go bad. Refillable carts/pods are generally the cheaper/simplest way.

As someone else recommended, going to a vape store is a good idea. Don't buy a super expensive one though, $40-50 is the max I would go because these things break.

Also mint/menthol is the best flavor imo.
