I purchased a device for university, hoping to utilize the colour e-ink technology, but it turned out to be quite disappointing. I expected a clear colour display for viewing diagrams, yet the resolution is so low that it's ineffective. The screen is excessively dark, necessitating constant frontlighting, which drains the battery rapidly (25% in just one hour). It barely lasts a day for my needs. Even more frustrating, the magnetic case included with the device interferes with the stylus functionality—you have to take off the case to use the pen correctly. (For more details, check out a YouTube video discussing the problems with the device.) CAUTION REGARDING RETURNS: Returning this item (in its original condition and packaging) would have cost me nearly 40% of the original price due to the company's return policy (customers are responsible for original delivery fees, receipt charges, and international return shipping costs). When I requested reconsideration of some of these fees, they showed no willingness to accommodate. (In contrast, another company provides a 50-day return policy with free shipping for returns...) In conclusion, I advise against purchasing this device unless you have done thorough research on its limitations and are completely certain it meets your needs.
