【Operation Confirmed】Playback Time: Approx. 3 hours
*Continuous Use Time: Verified on April 18, 2026, the battery level indicator showed low battery after approximately 3 hours and 6 minutes from a full charge. As stated in the instruction manual (photo 15), subjectively, I felt that the battery degradation was minimal.

*Purchased February 9, 2015: Ballpoint pen writing on the cover of the instruction manual (photo 12).
*Used for only about 1-2 months after purchase.
However, this is a used item that has been stored at home for a long time, so please consider purchasing only if you understand and agree.

*Rarity of Waterproof x Blu-ray: While there are many portable DVD players available today, models that are Blu-ray compatible and have a waterproof function are extremely rare. In particular, there are few alternatives for those who want to watch high-quality Blu-ray in the bath, making this model valuable.
*Stable ZABADY Brand: Twinbird's waterproof brand ZABADY has a solid reputation for use in wet areas such as bathrooms and kitchens, and enjoys stable popularity.
*IPX7 Waterproof Performance: With JIS IPX7 equivalent waterproof specifications, it is highly regarded for allowing users to enjoy Blu-ray, DVD, and One-Seg TV with peace of mind while bathing.
*High Demand Due to Weight: Although its weight and size (2kg) make it unsuitable for carrying around, it offers the advantage of stable placement on the edge of a bathtub, and is also in demand for in-car use.
*Waterproof Rating: JIS IPX7 equivalent
*Already discontinued (discontinued production), and while portable waterproof DVD players may still be available in some stores, Blu-ray compatible models are difficult to obtain.
