Apos

Company as a hole is good put dropped the ball on shipping. Payed extra for fast shipping and didn't get it and didn't even offer a refund on shipping

I contacted in customer service for some information about the Topping DAC/headphone amplifier, and there was a delay of several days in responding to me. Also, if I had known that the unit was being shipped from China rather than a warehouse in California, I would have purchased it from Amazon. I believe it took 7-10 days to get to me, rather than two.

APOS customer service is a train wreck !

Not everything requires an open ended response.

Received product promptly and in good condition. Billing was cort, but invoice was incorrect. Subsequent emails are a nuisance.
