Playing repeat from another post above. Being able to read charging amps on the controller's screen without having to use something else is a definite plus. Becoming familiar with typical maximum charging amps when required will alert you to possible connection problems, dirty panels, panel aiming or other issues.
I've used a number of the types pictured above for about seven years until the amps display stopped being included on what I could find. I have now used these, but only for a little over a year. Used with 100-300 watts of solar for personal camping and a number of electric fence charger installations for containing livestock. I have had no controller failures of any brands.
I no longer buy 10 amp versions due to sometimes needing to add panels. A 100 watt panel can sometimes output 7 amps. Also available on Ebay.
