It works without any problems. Immediate purchase is OK. You can use it right away. It has been disassembled, cleaned, and disinfected. It's quite clean, as you can see in the images. The battery life is good because it was used for only 4 months from new. I checked the inside and the soldering was done well, so I think those with maintenance experience will be able to use it for a long time. It's a BDM-030, so it's easy to maintain. Please understand the above, including the images, and no claims or returns are accepted. m(_ _)m ☆ We support both Yu-Yu Mercari and Rakuraku Mercari delivery services. (Yu-Yu Mercari will be used if there is no specific request) Rakuraku Mercari (Yamato Transport) also supports time slot designation, so please let me know when you purchase. m(_ _)m 4
