5 pens in total
I currently own 3 terp pen spectrums, 2 terp pen XL and 1 terp pen. The new spectrum battery's are terrible. The charge on it only lasts about 2 sessions. My pen XL will last half the day and the small terp pen will last all day. I have so many spectrum pens because boundless sent me 2 more to replace the battery issue. They suck. Battery wise buy the small pen. It works 10x better than the new spectrum.
