⚠️ Please read this as you may be penalized by Mercari. If there is a problem with the product, please contact me before rating the receipt. The receipt rating means that you have confirmed that there are no problems. I don't know the reason, but some people leave the receipt notification unattended. Even if it goes well several times, you will eventually be penalized. Claims that are not related to the product itself, such as mistakenly purchasing the item, are also considered as nuisance behavior (performance or compatibility). I will refuse to issue a receipt as it is not mandatory. Due to Yu-Yu Mercari delivery, date and time指定 cannot be set. Requesting earlier shipping than the scheduled date may result in penalties from Mercari (I ship within 24 hours if there are no problems). I try to be as accurate as possible regarding the condition of the product, but if you are concerned about minor details, please purchase a new one at a store. Operation confirmed. Everything in the photos is included. The side of the main unit is still wrapped in vinyl. The device version is 3.20. Deco M5 has V1 V2 V3 in the past, and 3.20 is the final improved version. The firmware also tends to be supported for longer than older ones. If the item doesn't sell for a while, I may relist it with the outer box. In that case, the price will be increased.
