I had basically 3 issues with this model: - The 2 "poles" on one part are too long, the parts CAN'T fit together. You have to cut them away. - hole diameter is too big, screws don't get a grip. I had to use bigger screws I luckily had on hand. - When I pay for a replacement part model, I don't want it to show the logo of the designer on the outside. - There was no text explaining that you have to print the parts mirrored for one side of the headset, otherwise the cable won't fit. - the outside is just a rectangular box. At least the edges could have been made round - it just looks cheap and not like the original. All in all no big flaws if this part was for free - but if you have paid for it, the demands are higher.
