We suggest visiting your nearest SealLine dealer to see which size E-Case works best for your device. We understand that visiting in person might not always be an option, so we've included the internal dimensions (length and width of the compartment) on the E-Case product page for your convenience. Generally, if your device's measurements are at least 3 cm shorter than both the length and width of a specific E-Case's internal dimensions, it should fit nicely, provided the device isn't thicker than 10 mm.
