Impressive run times and solid construction. I bought the dual charger that included 2 of these and recently bought another one to have an extra for my Senton 3s and Tenacity Pro 3s.
So far so good and I would buy more in the future. My local hobby shop runs them in their rigs too and said they haven't heard of any complaints.
The balancing cable worries me a little because it just hangs out there with no heat shrink protection, but I beat the heck out of them and no issues yet!
