Jens told me he was making an insurance claim and he would refund or resend when that had been completed. The package was never delivered, tracking showed no updates for weeks so claiming on the insurance was reasonable so I waited... eventually I lost faith in him ever sorting it out so I went to PayPal. I had emailed him back and forth over a few weeks with no resolution or update on the insurance claim. PayPal asked for these emails and the tracking details prior to refunding.
I'm not returning as defective as I know the product can work, I have a RR in a a1200 that works just fine. Also when using a CSMK2 the defective RR works perfectly. I also have a MK2 Indy that doesn't work so well but I'm not returning that either!
