I contacted 4Sevens about a Quark Mini AA R5 I received with an annoying high pitch noise on low mode, and an even louder and more annoying high pitch noise on medium mode, and asked for a replacement or credit if the noise is normal. Following is their response.
Please read Rule #12 All you really need to say is 4seven communication says the light is normal - Norm
I'm done with Quarks. I have several Quark 123-2 units that are great lights, but with all the thread problems with the Mini's and now the noise issue, I have moved on to a Nitecore EZ AA R5 and love the light.
No more Quark's for me!
