Ordered 5 hygrometers from these folks - website I ordered from inferred that this was an onshore company - these folks are based in HK.
Shipping took forever.
Products were defective - return process is ridiculous - you can't contact them via email or phone but have to go online to open a "ticket" through their site. You then get an RMA but are required to photograph the package, shipping receipt etc.
Still have yet to get my refund, just contacted them again today. Nearly two months since original order.
Steer clear.
