haven't used for long enough to give a real review.  Seems to be holding the system at 13.2/13.3 VDC with all lights and the furnace running, have never heard the fan come on so don't have a clue as to the heat sink temp or the current load on the converter.  Next  will be an ammeter and voltmeter in the RV system for some real monitoring.
Install was easy

I have not taken the time to use this device yet so my rating is middle of the road pending further use.

Hasn't been in use all that long but I like what I see so far. Hopefully it will prove to be durable enough to last awhile.

I have not had to use it for now.  I guess I will get back to you when I need to.  I'm using this as a back up as the last product I used did not work.  I cleaned it up and now hoping for your product to work.  Take care.

Haven't had a chance to use it much we're in a dead zone where we live so it is used while we are in FL winters. Used it for the first time today to call out. I'm still learning .

Well I'm giving it 5 stars because so far so good. I haven't had it long though, so can't report on how well it lasts.
So far it does the job and works well.

Have not had it long enough to really write a review.  I do like it very much so far.

I haven't had to use it, so I suppose I can't really do a true recommendation, but it was marked as tested as active!

Haven't had a chance to use it (& hopefully I never will), so can't comment on how well it works but appears to be exactly as described

It does what it's supposed to do, but I haven't had it long enough to rate more at this time.

So far, so very good, but I'd like to use it a little longer before giving a more thorough review.
