Have 3 of the INON and various S&S. The type 3s can use only the lower amperage EneLoop batteries, which should mean, but cannot confirm, fewer shots per charge. Recycle time is much better that the S&S I have.
Two S&S considerations. INON has shut down the USA service facility, and I no longer know where to get them repaired. I wrote to INON Japan months sgo, never received response.
The INON battery cap o-ring is definitely a weak point, esp. since the battery compartment isn't sealed from the rest of the strobe. A leak means a dead strobe. The o-ring expands with use, and will start slipping out from under the cap. If that happens, and you don't notice, dead strobe. I have an excellent example of such. Must carry extras and replace immediately.
I've never seen anything like this happen with the S&S strobes, and o-rings seem to last forever.
