I spent the week end playing with the old and the new pucks before sending the old one back to Tafée.
The results were very interesting, I'm gonna show you parts of the email I send them since I don't want to rewrite everything:
The airflow on the old puck is a lot more restricted than on the new one. I knew as soon as I took my first draw on the new puck and I even took out the stem immediately and put it on the old puck to see if it was the packing of the herb that was doing this but the airflow was back to feel restricted.
I guess that's why the puck would shut off when I was using the "press and release" method, sometimes there's not enough airflow to activate the sensor. Even if I do a pre-heat it would shut off and sometimes in the middle of the session when it should already be hot enough.
So far the new puck is working like it should, it only shut off one time and it was because I had slowed down my inhalation speed. Also I never do a pre-heat. (They asked me to do a pre-heating of the vape before the first draw, just press and release and wait for the heater to shut down.)
I was already in love with the Bowle but now with this open airflow it's on another level. Much easier on my lungs when I inhale, I have old smokers lungs so they can be picky and the old puck would leave me with a little discomfort in the chest because I would need to work harder to get my vapor. The taste of the vapor also took a bump and is better than ever.
I did some tests on the battery life using the same quantity of herb in both vape and using a stopwatch to make sure my timing was the same. When I did this last time the results were not good because I was counting in my head so forget what I wrote in my last message.
My results for the "press and hold" method were: OLD 4 cups and 3 puffs at level 1, NEW 5 cups and 3 puffs at level one and 1 puff at level 2
My results for the "press and release" method were: OLD 3 cups and 3puffs at level 1, NEW 4 cups and 3 puffs at level 1 and 3 puffs at level 2
As you can see I'm getting a full session more with the new puck. I always thought that the bowle should have enough battery life to give me 5 sessions since there's 5 cups coming with it and the Potter. The old puck would always give me 4 sessions at best, so I'm fully satisfied with this result. My battery life was even worse because of the constant shut off, all those 3-4 seconds heating weren't enough to produce vapor but they were depleting the battery each time so that's why I would always be taken by surprise when I would need to recharge the vape.
As for the button cutting off when using the press and hold method it didn't happen but I was mainly using the other method so it could still be a problem for me. In this case I think I might be the problem. I had several operations on my hands and as a results my finger strength can be a problem some days.
I did compare both buttons and they act the same way, if I press on them and slowly release the pressure the heater will cut almost immediately, it will take a little more time to continue releasing the pressure before the button will click. In my mind the heater should cut when the button clicks or at least right before it clicks. Right now for me it's too easy for my hand to relax a bit after pressing the button and have the vape shut off. Like I said this wouldn't be a problem if it didn't result in a need to recharge the battery faster, on a vape with limited battery life this matters a lot.
