    Lasted 5 months…
  

*by B***S on Reviewed in the United States on November 16, 2022*

Lasted 5 months and then stopped charging my batteries. I wanted to like this but I had to replace it.

### ⭐⭐⭐⭐ 







  
  
    Seems solid so far....this a couple of bumps and notes.
  

*by G***X on Reviewed in the United States on February 1, 2022*

Have had hooked up for a week so this will not be a longevity review.Seems to be working normally.Couple of Notes: The screws in the bus attachment are not the greatest quality, they're ok.  The location and size of the screws makes it a bit difficult to find the correct size screwdriver to fit.NOTES: I wasn't sure which way the screws were supposed to turn to open.  If the metal lugs are all the way to the top, as-in the hole is mostly open, you have to turn the screws COUNTER CLOCKWISE to get them to come down on the wire attachments.  This should have been noted in the manual.Also, the manual notes a "key" you have to use to change the battery type.  This "key" is actually a hole underneath where the led display is at.  A tool/pin used for a cellphone can get into this hole.  You hold it in for about 8 seconds and then when flashing you again press the button.My unit was described as coming with the LCD display but did not.  CS sent me another unit which also DID NOT come with this display.  HQST ended up sending the display separately.  The display works as indicated.  It provides current information but does not seem to log this information over time unless I am missing something.As I am currently using this with flooded lead acid, I can not speak to other complaints/reviews with it's use for lithium.  I hope there is no issue as this flooded lead acid I have been using will probably be the last.I will update this review later if I run into any issues.  I am currently only running it with 1 of 2 100 watt panels, so I'm hardly pushing it.

    I had problems with customer service with another brand, bought this, works so far.
  

*by R***S on Reviewed in the United States on July 21, 2022*

Installed with 100w panels from the same mfg. The system was easy to install and works great. No  chance to test on a trip yet. I had another product, but got li battery and had to change. Tech service from the other mfg. was slow and difficult to work with. Decided to try these, no need for tech advice so far, but good out of the box.
