* IMPORTANT: All EZ-Robot items are shipped directly from the EZ-Robot plant in China to your shipping address. The ordering method of EZ-Robot stuff is therefore slightly different than normal: place the desired EZ-Robot stuff in your shopping cart, then enter your name and address and skip the payment: just let us know how you want to pay (bank , paypal). We then send the order data to the factory where we receive the correct price (including shipping costs) from them. We will let you know asap (speed depends on the EZ-Robot company), as soon as you have made the payment we will order the EZ-Robot factory to send your order directly to your shipping address.

Additional costs: you may have to pay customs (import) costs before you receive your order, this depends on your order.

This is the fastest way to get your items for a low price. EZ-Robot uses this method to get the costs as low as possible and in this way you always get the LATEST version of your EZ-Robot item (s) !!!

*Note: Verify in EZ-Builder the current EZ-B v4 comm version to see if this upgrade applies to you. After connecting to your EZ-B v4, look in the popup status window at the bottom of the screen, or add the Debug control. The EZB v4 version will be displayed in the connection debug log.
