Terminal "busted" hence could not even try electronics. (edit: 2nd try still 1 if not 0 stars)

Terminal "busted" hence could not even try electronics. (edit: 2nd try still 1 if not 0 stars)
I received this weeks before the battery and all components. I was going to run not only proper cable but breakers in between. Lo and behold the day I got the battery I went to begin wiring and what did I find. At least one terminal completely unsalable. The screw is stripped, out of alignment or something. Because its all encased I cant even attempt to fix without breaking the casing open. It looks like something was done prior to my ownership as even the case is lose. Probably for the same reason the terminal is screwed up. In effect this entire unit is useless. Note the picture of the separation of the part of the unit case, its not like that on the other side. I was going to buy a 150+ dollar unit but saw good reviews of this and figured I'd give it a try for my first "mobile" solar build. HUGE mistaken. Guess you get what you pay for. I will be pursuing a full refund and go with an entirely different brand. One that doesnt have in accessible terminals so if things go wrong I at least have options.EDIT: (I really dont like giving negative reviews.)I chose to get a replacement instead thinking maybe just a bad apple. While I received the replacement very quickly on first setup something already seemed off. The battery capacity indicator was slowly but surely dropping off. Maybe 1% every hour or two. This is with NO loads and plenty PV. I thought it may simply be the accuracy/method it uses to measure so did not think much of it. Over a period of two weeks I tested the system perhaps 4 times. All with the same results. ie: Everything looked fine but this odd drop in the capacity item. Approximately two weeks later I set the system up again to charge my gel battery but the unit would not power up after connection to the battery. Checked everything from cables to breaks to putting a load tester on the battery. Zero problems. A trickle charger topped the battery off in less than an hour. The unit still wont power. Connected to another battery. Still wont power. The unit literally died sitting a few days doing nothing at all. I think two chances was more than enough. Time for a different brand and unit. Had this worked it would have been very nice. I hate starting over. I am sending this back for a full refund.
