Summary: Drawing is difficult with this pen.only one size ball point pen size.med 0.6 or 0.7 med pt. its neat to see what you draw appear on your iphone/ipad.it does what it says. That said, its not that great. The physical pen is thinny and boring and hard to use. Because the pen is non grip formed. No tapered tip for fingers to grasp. It just doesn't feel right. Ii returned mine.
Summary: I don't think this is a great product. The pen isn't comfortable to write with, the ink doesn't work well and the software that came with the pen is extremely dated and difficult to use. I think this pen is very gimmicky and I threw it in a drawer and haven't used it since the day I got it.
Summary: Order 1 unit from Amazon, received a defective unit. Communicate with IRIS directly for replacement, they ask me pay for the return unit postage to Belgium. Plus, after their technical team verify the defective unit, only will ship a new unit out to me. I decided to perform RMA with Amazon. At least Amazon ship the unit prior I return the unit. Regret to buy it. Don't know the pen can last for 1 year or not. Lost confidence with the product quality.
