Please only use English character shipping address. Otherwise, the UPS system won't be able to process the address.

Please note this is a final sales, Cancellation can not be processed.

Important: Do not over-tamping. Start with small number on the depth setting number. Over tamping makes noise “clank… clank” a sign the gear out of sync. Check the FAQ.

Please note that buyers outside the USA might need to pay customs and any import fee.

This version does NOT work in a bright, very sunny place, so it might not work well for an outdoor coffee cart that directly gets a lot of sun.

There is NO warranty, but we offer remote support to get optimum functionality. Some main  components could be sourced in Amazon.com (ie. battery).

This promo is including the Wireless charging pad.

Here is the charger that works well (tested), strongly recommended:

• Apple MagSafe Charger
• Baseus Wireless Charger for Magsafe15W Mini
