Purchased and delivered quickly, thank you Amazon perfect packaging. As for the product I find it very good for casual use this plastic but good presentation. A little adjustment period to learn to use it properly and all is well. I tried the 100-400 with his own foot ring (it is mentioned in the manual "in Englais" the maximum weight that can withstand the Lens2scope is 800 grams) .I also tested the 60 cannon macro with the foot support ens2scope fine. Besides very happy with the brightness for 2 lenses tested, 10 X magnification (I have not tried the ratio 1 "25X" - that's for later). Use seamlessly with the 100 - 400. (magnification 10 to 40 X again according the user manual). see the buds of a tree 30 meters it's fabulous. Of course we must use a foot and be either even stable, as soon as you touch the foot there is visible vibrations despite the quality of the foot. It is better that the subject is fairly static since 400 and close it quickly out of the field, but I said it's for occasional use. Focus sharp but satisfactory dot. For me the quality / price is perfect.
