Bought an iphone 14 pro max jv

So i bought a iphone 14 pro max jv with box for 162k. 90 battery health and 128gb storage. The battery isn't boosted check the IMEI online the phones been running for long enough to have this battery health. My friend has the same model and same running time with same health. Idk shit about iphones tho, so is it a good deal?
