Suitable as decorative element, but not terrible as bottle opener

I bought 2 and the lack of precision in the manufacture fact that it will not make a good opener.
One is unusable second works moderately. we must try several times to uncap a bottle.

By cons, it matches the picture and fits well in a suitable environment
(On a beam of an old barn that is used occasionally to party in my case)

Having to uncap the bottle up, is also losing fluid.
Conventional wall openers do not have this problem because it decapsulates going down so that the bottle is upright when opened.

I takes only 2 stars even if I am satisfied with my purchase, because I think that objects should at least fulfill their utilitarian function correctly.
