It's hard to beat Blue Sea Systems components in the quality department. They are more expensive than some alternatives but they are well designed and durable which, in my opinion, makes them a much better overall value. The unit included clear instructions and useful specifications such as torque values, precise dimensions, and maximum volt/amp ratings. I trust this brand to deliver a product that is sturdy and safe to operate.

Don’t cheap out with electrical, spend the extra $20 and do it right with this fuse panel. Everything works as it should and it grips the fuses real nice. Very compact, perfect for tighter builds. This was less than $40 so I’d consider any quality electrical for that price to be a good bang for your buck. Understand that THESE DO NOT COME WITH FUSES, But I just kinda figured that was standard and bought the fuses I needed separately at the same time.

Picked this up as I was rigging out my Matecumbe 169. I dont need a lot of capacity, as the only connections that will run thru this are nav/anchor lights, GPS/DepthFinder, and a manual switch for my bilge pump.Two screws mounted it, I ran to the main power cutoff switch, with a fused link in the power cable, and ran the negative lead to the battery. I like that the ground was a part of the unit, removing the need to run a separate block for the black wires.Comes with little stickers for noting what is wired to each connection, but if your handwriting is as bad as mine, you may want your wife to print the info on them. LOLSeems like a fairly well constructed piece of equipment, so i really expect no issues with it.Overall, no complaints, other than the fact that Im too old and stiff to work inside the confines of an enclosed skiff locker.

Update 7/7/2020:Ordered a replacement via amazon that arrived the next day. I had originally contacted the distributer on the recommendation of amazon and have yet to get a reply. So I just returned the original unit and purchased a new unit. Same outcome, just faster.The new unit is working great so far with my 24 volt battery bank. Hopefully it was just an isolated quality control failure.I have connected the main #10 post terminals on this fuse block to busbars on my battery box using 4AWG wire with #10 ring terminals. The 4AWG wire fits well and the cover clears the wire without needing any modification.The posts for the individual circuits are #8 so I have connected each of them using 10AWG wire and #8 ring terminals. There is plenty of room allowing the cover to clear everything nicely.The additional wires on the posts that can be seen in the original photo I posted of the failed unit are leads from a 24Volt battery charger/power supply that is fused separately.The photos contain the information I found on the Blue Sea website that shows the dimensions of the 6 circuit and 12 circuit fuse blocks.Original Review; This seems well made for what it is and made for a clean install. I am concerned about the quality of the electrical components since one of the six circuits was dead on arrival. The same wire and same fuse work in all of the other 5 circuits but do not work in the number 2 spot. I will send this one back and order another hoping my experience is an exception and not the normal, either way it is not very confidence inspiring for an electrical safety device to come new with a failure. I will update the review after receiving the replacement and returning the faulty unit.

I've used Blue Sea products over the years. I never had any doubt about this product as I had a need for it on a current project. Fit, form, and functionality are spot on. It's a good buy.

This is probably the best small fuse box you will get for a boat. High quality fittings, stainless parts and useful little labels. The negative bus means wiring can be kept very neat too. It also holds spare fuses.

Blue Sea makes great stuff. Used this as a second 12v fuse block in my RV for Starlink, a router, and a Rpi for monitoring my solar panel system. Works great.
