This was poorly manufactured, particularly with regard to the connection between the top and bottom halves of the unit. Phone calls to the maker's customer service line went unanswered and voicemails were unreturned; months-long email communication chains resulted in two duplicative sets of connection hardware being sent at different times, which did not address the actual issue in any way. Had I not ultimately paid someone to devise an alternate, more secure solution, it would be highly unsafe.
