I bought this the end of March 2026 from Amazon after watching a video review. I was very impressed in what the ISDT FD-200 Lipo Discharger could do. Late spring I started flying my RC planes and was amazed how quickly the discharger got my batteries to safe storage charge. Yesterday I pressed the current select button to start a discharge process and the FD-200 responded as it should. I then noticed that the button had remained partly recessed and not flush with the front plate when I was ready to do the next battery. I pressed the recessed button and it fell backward into the unit. I removed the back plate and the button fell out. I emailed the manufacturer and they responded telling me to contact Amazon. Amazon told me that too much time had passed for them to do anything and to contact the manufacturer. Four months has passed and I now own a useless ISDT brick. Buyer beware!!!!

To use FD200 one needs the "ISD Go app". Unfortunately this APP does not run Android 15. So FD200 is usless for me.

Unfortunately, ISDT abandoned android user. About from half of 2024, ISDT haven't able to get work ISD Go app on Android 14 or higher and looks development has been stopped. And I send e-mail to ISDT but they ignored it. I strongly recommend DO NOT buy FD-200 when you use Android14 or higher or you planning to buy new android phone.

The bluetooth function does not work. I've tried with different smartphones and different app versions unsuccesfully. The ISDT support was irresponsive to my request.
As discharger, good, does the work.

Great discharger, works perfectly, a must-have for Lipo batteries
