But for non-top 5 hotel locks, if the model have a visable cylinder cover(a hole of cylinder, to insert key), it should not be easily get drop out.
This is always a headache for many hotels.
After a long term using, the all cover on the lock was gone.

Some look top-heavy, some like a sword, Some are like coffins.
Strange proportion-likes a big head and a short body, or a small head on a very long body.
Human beings have something in common about beauty.
7.An EPS filler in packing box.
Hotel locks are bulk purchase, it does not need a pretty look packaging. Color printing film – coated packaging will impact on the environment. Meanwhile, The shock-resistant filler must not be non-degradable.

8. Gaskets under handle is visible
This is a very tiny details, but it says something about attitu
de of hotel lock manufacturer.
