Good lamp with gravierendem lack in detail

The lamp should replace our 400W Torchiere who acted rather than heating. Of course, only LED came into question. I had looked at the lamp only in a furniture store. I'm willing to pay a little more in the domestic dealers, but not less than 200, - which should cost the lamp in the furniture store more.
The lamp was unbreakable packaged, with the crumbly Styrofoam is still longer in my apartment be found.
The construction is "actually" not difficult, but you should be with your partner. First difficulty was turning in the second leg segment (the one in which no cable runs). This is done by means of a fairly coarse thread; Despite great effort, it initially could not be as necessary until it stops. I have the thread then wetted with a touch Teflon spray, then it went. I ask myself only ever as a technically untalented and poorly equipped grandmother (her other grandma: Forgive me the generalization!) Can handle it. Otherwise there is not much to do.
The attached 19-key he is indeed "lummelig", but met for the unique tightening the two nuts in the foot its purpose.
But then there is still at a very small Allen key. The is used for fixing / adjustment of a tiny grub screw on the hinge on which you can adjust the tilt angle or the friction of the reading arm. As this reading arm Loosely hanging down, I wanted to stop in. So soulful turned on the small cog. Since no instructions came with it, just by feeling, but after two turns the screw was over and the little screw was lost irretrievably in the lamp housing! This means that the lock / adjustment possibility was gone! Fortunately, I had a small regular slotted screw with the same thread. So that I could help me, but with foreboding, as I am not sure if I thus reach as provided with the grub screw same effect. I have the reading arm now fixed in a position that I will probably use most frequently - is not the best.
It is annoying that the customer is not warned about a manual that he may turn the screw only to a certain degree. Actually, would a normal screw with head (and thus with stop) have been eh meaningful.
I had the lamp indeed can return - but dismantle because of a 2-cent Schräubchens everything again, packaged, the strand of cardboard to UPS or to the post office?
Otherwise, the lamp is chic, the light output is not quite as hoped (could be in the furniture store with the many ambient light does not correctly assess) but adequate, especially as I now, unlike before, have a separate reading light.
The housing of the reading lamp head had started something and had a small scratch, but since I'm not soo picky.
So: The purchase leaves me ambivalent. Actually, a good, successful also in design product for the price I would have liked to see more sophistication in detail.
