Reliable DPDT switches?

I was wondering if anyone could recommend a quality DPDT switch or and where they get them from. I have used these from a seller on Amazon and have had to replace 2 out of 4. One didn't work out of the box and the other 2 started giving me issues a few months after the install. Needless to say, it is a pain having to go back in and replace these. I'm planning on ordering another batch but want to get some feedback before I do. Thanks
