TEP 1 in 4 Out AGU Fused Eye Candy 0 4 Gauge Power Distribution Blocks Block 12V Car Truck Mobile Offroad

This does what it's supposed to do and is pretty compact for a four-way distribution block that does both positive and ground. However, the lights don't seem to turn off when not in use. I'm afraid it'll drain my car battery after a while of being parked. There are blue lights under each fuse slot that light up when connected, as well as a display on the corner. All of that is always on for me. Plus the voltage indicator doesn't seem to display anything useful. My capacitor has a voltage indicator that works, and the readings on this block don't really make sense. That's fine if you have the block hidden somewhere, but it still doesn't solve the issue about having blue LEDs always on and constantly draining your battery. If the company doesn't reply with a solution, I am going to return and try something else.EDIT: The company replied and explained that the LEDs have a low enough power draw that it would take several months of being parked to drain the battery enough so that the car won't start. It's also possible to unhook the LED wires inside the unit if you're really worried. I increased from 3 to 4 stars for this because this block is a great space saver for having both positive and ground in the same unit. I have 10 fat wires hanging out of this thing, and it's still stashed under my seat (in the seat, not on the floor) without any space concern whatsoever. Plus my car is small (2017 Mazda 3 GT).

The good:- Run all power and grounds from the same place. Should reduce the possibility of ground loops.- Heavy, substantial. Not easily damaged.- Works with a variety of wire sizes. I got some wire ferrules to assure better, cleaner connections.- Individually fused outputs with LEDs to indicate if the fuse is blown.Cons:- As stated by others, the built in meter and LEDs are on constantly. Since this is going on a weekend driver, I was concerned about long term battery drain.- The tabs to retain the fuses were splayed too far apart to even keep the fuses in place. Had to use needle nose pliers to bend the tabs inwards to give ample grip the fuses.I solved the constant ON issue using a relay (https://smile.amazon.com/gp/product/B00MMY3A86/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1) which fits under the back cover of this distribution block. By moving the LEDs/meter ground wires to the output of the relay, I can switch the LEDs/meter using the same remote signal which is turning on the amplifiers when the stereo powers up.

Seems to work as advertised but Mine is defective. I installed the unit in my vehicle but just tried to hook up the wires. I purchased this a couple months ago but can not use one of the positive terminals. The set screw is frozen in place and won't move.If I can get a new end piece for the positive side I can install it and I expect my experience will become a 5 star.Also hope they become available again as I would like to get another for my truck.
