Product was defective and the support team wanted me to give them a 5 star review in order to receive and advanced replacement.I installed Ubuntu on the device but the wifi did not work. Contacted support and they said I needed to replace the device. They did not provide device drivers or any other tech support.The device would also randomly freeze and would require a manual reboot to recover. This would happen every 12-24 hours. Support did not provide any support for this at all.Customer service refused to give me an advance replace unless I gave them a 5 star review on Amazon. This is them buying positive reviews for a product they seem to know doesn't work well (why automatically send a replacement without doing any troubleshooting?)Shocked that they wanted to buy reviewed I declined all replacements and shipped it all back via Amazon. They wanted to work the returns out offline and not through amazon.So defective product, poor support and very questionable business ethics and practice.
