I did not experience any real noticeable effects from this product. I took two capsules every morning. I felt kind of short fused, or easily agrivated while taking this. Went away a few days after I stopped taking it.

The user interface takes a little bit of getting used to, but seems to be relatively simple and ad-free compared to that of the Xbox One. The ability to put apps (i.e. Netflix or Amazon Prime) on hold to open another app or navigate through the menus is great.

They sold this model as a SEK-1000/ZA, but when we received the box the original label said SEK-1000/ZX. They had pasted a new label on top of the original with the "ZA". When I looked it up, it seems that this product is actually from Panama and is NOT the U.S. model.

I ordered these expecting them to be just serviceable, to cover a plain steel wheel. I gotta say that, especially for the price, these aren't half bad! No you're not going to confuse them with the $80 a piece factory caps, but they're actually pretty decent quality. They snapped onto the wheels just fine and appear to be holding sturdy. Time will tell I suppose, but for the price I paid they could all fly off 6 months from now (not saying that they will) and I'd still feel it was a good purchase.

This little device is a must for all astronomers. It does an injustice to show a picture of a child looking thru it. I think this would be a an appropriate item for all astronomy majors. It shows all the constellations for both Northern and Southern Hemisphere.
