Good but
"This is really a really good quality product as you would expect from Shimano. Freeshift function is the the best thing. Been using this derailleur a couple of times so far (about 60miles) Good product but today it decided to stop changing gear, it just beeped and was stuck in 11th gear! I was nearly home, pretty flat terrain so I just used boost mode. Once home as I was riding real slow around the lawn it started changing gear again 🤷:male_sign: I have no idea what’s going on. Will see if this problem happens again, maybe it was just confused 🫤."
