I had looked at many reviews in advance and videos on Youtube about this Stylus and was looking for an active stylus with thin, hard top. I have now tested him two weeks three apps (Good Notes, Paper by 53, procreate) and have to say that processing and Ideas convince the volume when writing, which was often criticized, I do not feel as a disadvantage. However, the implementation is sometimes so bad that the device is to use limited. I wanted this Stylus mainly to make notes on transcripts. For this you would have no stylus with pressure-sensitive tip needed, but I wanted the model without batteries and also harm it does. In any case show in this application some weaknesses that lead to the fact that the pen can not be used reliably and without any problems, which would be important in transcripts and the price of course: - The palm rejection, which will allow the placement of the ball of the thumb when writing, working with the adonitol own solution - rather unreliable, which is certainly also depends on the users (> adonitol SDK in Good Notes). Anyway, it is still prone to failure and deletes all possible settings (sensitivity, hand position -> Good Notes) characters and lines that are no errors. Also marks the markers are cleared again and I have letters, etc. make sometimes three or four times until it will not be deleted. In transcripts you have not this time. In addition, the SDK creates adonitol always an offset, so you can stay hard when writing on the line. The palm rejection is, the worse the farther one goes as right-handers to the right of the page. I use a Bamboo as passive Styles and here works the palm rejection of Good Notes itself actually better. The Support of Good Notes has confirmed some of my criticisms and pointed out that adonitol will soon release a new SDK that will be incorporated in an update in Good Notes. - The problem of zigzag lines during slow drawing diagonal lines is actually, even if you used a passive stylus when produced bluetooth connection. So there must be more likely to be a software problem. For precise sketches or drawings which is more of a hindrance. Well short of the mark Apps: Neither Paper by 53 still procreate support adonitol SDK for palm rejection. So you can hang up the painting and drawing the palm NOT. The pressure-sensitive tip is a great feature for creative work and doing my opinion what it is, quite well. But what makes working here for me impossible, is the offset, so the offset between the point where I put the pen and the point at which a point or line is created, I hardly wegbekomme. It is virtually impossible to accurately draw for me as I never know where the next line will be placed when I once sold. Despite the beautiful pressure sensitivity it is therefore possible, in my view therefore hardly work properly. To this long, but hopefully helpful to complete review: My curiosity about a great product was rather disappointed because the ideas are all well and indeed great, but the implementation is still much to faulty and unreliable, so it currently is for me rather to the level of a nice gimmicks that I do not use so professionally may, as I wanted: fast, reliable and uncomplicated.
