I'm an artist and professional graphic designer and I have no idea about these negative reviews. I recently got the ConceptD from Acer, and while it comes with its own stylus, it's a tiny little thing, too small in my hand to do anything more than a quick sketch. I almost bought the regular Bamboo Inks but after buying this stylus, battery and charger it's almost like buying this newer one. No problem, it's accurate, stays connected and feels secure in my hand. I've tried it in Photoshop, Illustrator, Sketchbook, ArtRage, Flame Painter, Rebelle, Adobe Dimension and I haven't been disappointed with its performance. The battery lasts much longer than I expected. I've only charged it once (last week? two weeks ago?) and it's around 50%.
