...somehow my tv strawberry cheesecake liquid went bad and tastes like sour milk.
That's so funny I can't even think of a come-back line!!
But back to the business at hand, I only got 145 puffs on charge #4, so I know now that the 2 hrs. and 10 min. was not a full charge... and that it probably didn't like being interrupted when I took it off to show my neighbor...
That being said... it got/took a full 2.5 hrs. on the next charge, and gave me 175 puffs!! At 165 the vapor got a little thin so I added just a few drops, but I never let it get to where it was completed drained this time.
I still think it's amazing that the pre-filled cartos last as long as they do!! I can only get to about 110 with a refilled one before I need to top off, and even that's pushing it...
I know I have said that I'm not wild about the taste of the menth, but it's not unpleasant, just a bit strong for my tastes... (out of the 5 that came with my kit, I still have 4 left!!) And with the combo of my 555 menth and the PB/SS carto, it's perfect for me!!!
I have been using my 510 auto (with the atty and cart) when it's charging because that's what I have that most closely resembles the length and draw of the PB... but my 510 seems stiff now in comparison. I do like the ease of changing flavors with a carto, too, but now the PB is the best of both worlds!!
It has the reliability/stability of a manual batt, the ease of changing with the carto, and the length and feel that I love!! What more could I ask for??

(except maybe a Pink SS batt to keep it company... <tee hee>)
