It is disappointing. I haven't been long acquainted with FiiO, but I do like their products. I noted earlier in the thread my frustration with some screen defects on both the FiiO M11 Pro (returned) and FiiO M11. I decided to just keep it because it's not something that interferes with my ability to use the M11 (its what I would describe as a ghost rectangle that hovers in the middle of the screen). Plus, its gotten better to where I only notice it on certain colored backgrounds. I also the BTR5 which I love and a cable for IEMs from FiiO.
All of that to say, I like FiiO products but their customer service is like a broken record at times. Usually, its silence, but then when they do reply its "We're sorry" (which is appreciated) and "Would you like to exchange it?" I'm not a big fan of having to play the exchange game on products, especially on minor defects.
I don't know, I've had outrageously good experiences with customer service at other tech companies and they put FiiO to shame. I've had companies, with major defects, go "We'll send you a new one" and they let me keep the old one - I mean, its basically garbage because of the defect, but at least I don't have to go through the hassle of returning it, waiting for them to receive it, and then send me a new one. Even for minor defects or frustrations, like this screen defect would be, they've given me the option to either a) send it back to be fixed/replaced (which FiiO does), or b) keep it and receive some sort of incentive (which FiiO does not). Granted some of these companies aren't purely audio related. Like Garmin, I had an issue with the stock-band not fitting right (it was too small) and they sent me a free one ($60) no questions asked. Drop.com - my HD6XXs were delayed with everything going on. I reached out to customer service to see what was going on - wasn't upset or anything, just wanted to graciously make sure they didn't get lost. They sent me a free pair of their Stride earbuds. I'm not the type to go off on customer service to get what I want, but I also notice when customer service does a good or bad job.
Maybe I'm being entitled or expect too much, but (again) with something like my screen defect on the M11 Pro (which I sent back and got the M11 instead) and then the slightly better but still noticeable defect on the M11, I don't want to have to keep sending the product back and forth in the chance that this one might not have a defect. In that case, if FiiO was like, "Hey, we realize you paid a lot of money for this, would you rather send it back and get a new one or would you like ____ on us (a free cable, case, BTR3, whatever - something that probably costs them close to nothing to manufacture)?" If FiiO had done that instead of giving me the cold shoulder and then eventually replying with a boiler plate response, I'd be singing their praises right now.
