My wallet is super burned now that I also bought the Tronxy X5S xD. I decided to buy a 100W solder, and with my old 25W one, fixed it in 1 minute.... lol. My soldering iron wasn't strong enough. However I found on Aliexpress lots of ones that came soldered, so next time I might just do that lol. However I did learn how to solder properly and have the proper tools now.
