Nice feature is the fuse

Appears to be a very well constructed cord.  Nice feature is the fuse.

Easy install if you have basic wiring skills (red is positive, black is neg) and a fuse add-a-circuit that fits your fuse box. Lights get power when my car turns on and off when the car turns off. Clean colors and the 'beat to the music' mode works quite well if you position the control panel correctly.

This little fuse was a bit pricey at ~$4, other than that, this fuse works for its purpose and was installed on my 2006 honda accord.

I like that it has a on/off switch that isn't easy to hit by accident.  haven't tested the surge protection

This works a treat to replace my old barrel fuse block on my XJ650. Only complaint I have is the cover was cracked when it arrived but that's an amazon shipping problem not a product issue. The spade connections are nice and tight and all in all it does what it's meant to so far. Note that this is not meant to be a one-to-many - it doesn't have one single ingress power feed it's meant for 4 separate inline circuits.

I does come with the fuses you see but I replaced them with glow-fuses that you can get on amazon or from any auto-store. They glow when they blow so that's very handy.

I was weary of buying this at first because of all the comments about it blowing fuses. I checked my Honda Accord Sport and it has a 20 amp fuse i think for the accessory outlet, so i had no problems using it in my car.  Used it on car and motorcycle and followed instructions on starting the engine before turning the compressor on... so far it works fine. hope it will last the test of time.

It's more expensive than just getting your own inline fuse holder and putting in your own fuse, but it's definitely more convenient.

Like the design remove the cover place the fuse place cover back on. I haven't had any problems using it with 4-AWG HEAVY DUTY wire cable.

It could include a fuse holder.
The fixing belt shown in the picture is fragile.
The output power is very good, providing fast charging, much faster than the majority chargers avaible.
The USB outlet attachment is tight, which is appropriate for the bike vibrations.

I needed these fuses for my landscape lighting setup.  Don't understand why the mfrs continue to use "old days technology", i.e., fuses, instead of circuit breakers, but they do.  That said, these fuses are exceptionally well made, and they have a DUAL-ELEMENT.  I've not found another fuse that has this neat feature.  One element is a stretched spring.  The other element is the more standard metal strip.  If the spring is shrunken up, that means there was a circuit overload.  If the metal strip is melted, then the problem is a short circuit...Really helpful!

Fuse does not last long before it blows and has to be replaced.  Fuse should be more durable and last longer.

This little gizmo works exactly as described, the only thing I think they should add his instructions as to which slot is the fuse for the new wire and the fuse for the existing juice box.

Another reviewer (steve) included a nice little drawing to explain which one. the company could almost use his drawing included in the packaging. I have attached a copy of his photo here

It was hassle free and easy to install, it comes ready to be hooked up to the fuse box for a proper and professional installation.

This unit will do the job I need it to do. It would have been nice if it came with the fuses.

Slots for fuses are really tight, so care is needed installing them without breaking the plastic casing.

Packaging was so so. The bag wasn't completely sealed, so was missing a couple of fuses.

Other than that, does what it's designed to do. Nice gauge wire and heat shrink is nice and clean.

The only downfalls is that some of the parts seem to be cheaply made like the fuse holder. Problem solved with a little electrical tape wrapped around it though. The wire is not completely true 4 gauge but i promise that if you go to a store like quality auto sound or car toys they will have a completely comparable kit at twice the price. Not going to use it for competitions but a good choice for my girlfriend who does not compete her system.
