Lustery E1502 Nicole Kitt And Jonte Collar And Upd 🚀

For the UPD, how far is the range? Can it be used in a large area? Does it have multiple correction levels or modes? Maybe it's compatible with different collar models. Also, the charging time and battery life would be important. If the collars need to be charged, how long does that take, and how long do they last on a single charge?
