I've had my Itaste vtr for almost a month now using the IMR 18650 battery and the supplied clearomizer at 2.5 ohms. The longer I vape at 8 watts, the ohms increase. From 2.9 to start to almost 7.9 ohms after about a week of daily all day vaping. Is this normal? I've never had a unit before this one that registers the ohm amount, so I'm not sure. Or am I just doing something wrong? I assumed the vtr would adjust the proper power on the watts setting. So? What's the deal? If you know, please advise. Thanks!
