I am a little disappointed with this article for two reasons: the first is the drawing above which is approximate (the design is a little disorder as an enlarged photocopy with poor quality), the second is that it is much too big! While storage is aprciable, the height is good but excessive length (I can go an A3 sheet at ease). I wish that there are shorter but even the lower model version is too large) ... Too bad ... If the product is durable.
