TonePros LPS02 C Tune-O-Matic Set

I bought this set because I saw many times that TonePros was a trustable brand.
When I got it, there was issue with the stoptail. The post'screw didn't match it. So...I tried to filed it a little where it was blocking. but still need too much strength to make it assembled.

Note that the chrome finitation is just a layer. The real material looks to be bronze or laiton (orange like metal).

I contacted support, sent it back and got it back. The ticket was rejected without any information or answer... I had to connect to my account to see it as rejected.

That's the game because I filed it, but I would have appreciated at least a mail to say "you broke the guarantee". so...

so..not happy by the product, especially regarding the price and from support's communication.
