Two doors .velos damaged during shipping, packaging problem!

This is undoubtedly a very good bike carrier, even as Amazon-should be capable to deliver an undamaged copy to my home.
The first commissioned on March 12 arrived on March 14 at my home, failover system via a knob being completely useless. Referred March 15, I was refunded within three days. I have not been able recommended because I had received the last copy.
On sale again, I order a new copy of the same bike rack on March 25 and it happens to me today with the "indulge in a day". The board of the latter is completely gutted. My wife who receives the parcel has reservations when delivery. And because when I finish to open the carton to my home from work, I find that it is damaged at its base and one of the two completely distorted media.
The problem with this bike rack is its nonserious packaging. Obviously one bicycle door that weight floating in a too large cardboard without any protection on the inside, like bubble wrap, styrofoam ... can cause such problems.
I will turn to the same model bought in a store.
I therefore recommend this bike rack but not purchase on Amazon.
