I agree with previous reviews stating that this accessory is bulletproof. It holds very securely to my eTrex 20 x . In reading the other reviews, there is a certain degree of belief that the handheld should be hanging upside down in order to facilitate an easier read when turned over. Is this a design flaw? Regardless of why it was designed that way, I am using a work around which works well, at least for me. As I generally hike with my day pack, I installed a metal swivel (pictured) on the waist belt. These will cost about $2 at any hardware store. This enables the eTrex to be more easily turned for better readability. Without the swivel I found it a bit awkward. Now, although not ideal, it is a marked improvement.
