Interesting idea, to improve product

The idea is interesting: to make freehand drawings, sign and integrate the results in formats such paint in your documents ...

Only the product is a little "just" for this.

The inner plastic thermoformed packaging is a bit stingy. The user manual is in English and not very precise nor very detailed on the usability of the product. There are two guides one to a mac for windows.

Contrary to what announces the guide, the pen is provided without AAA battery so it must have on hand or wait to go buy one.

Then there is a product which requires the installation of a pilot by a CD which indicates that this is a rather old-generation product. There problems: first the CD was unreadable, then the driver that I downloaded from the creator of the site does not correspond to the product. Normal, the guide is a guide for 4 or 5 products of the same range, for which product you have, you must return the box, there I saw that I had the H420. I did download the correct driver from another PC and install the driver is on an external hard drive to finally try it.

There I opted for a drawing in paint. The paint page is smaller than the tablet so it does not draw outside an unmarked on the tablet surface.

Then I saw of adjusting the thickness of the line but it seems like a gimmick because the real problem is that the result of freehand is very "shaky" and absolutely not comparable to a plot on paper. Even a simple initials will be difficult to use.

I fear not having the utility of this product. Maybe would it true user guide and especially solve the problem of installing the driver?
