It is definitely an improvement over the original Spider Pen, but it still has its issues. I don't like that something labeled "Pro" requires an "adjustment" to keep the battery connected. Also, the "silver" finish easily scratches off. I do like that you don't have to touch the pen at all during your routine. The IT also seems pretty strong and it is a lot easier to fix a break than with traditional reels. Over all I would say the pros outweigh the cons, but it is pricey for what you get.
