You can't go wrong with Blue Sea!
After upgrading the alternator on our vintage RV we needed some stout wiring and a much larger fuse, enter Blue Sea 5001 and a Blue Sea 200 amp fuse. As usual, install was super easy, and I cannot see any issues with the lasting forever! Blue Sea stuff is super high quality and we have used it all over our RV. In the image there are two other Blue Sea products! For the price this is perfect!

Quality. Lid stays on
Works! I had to put a mega fuse on it and connect it up to my lithium solar configuration in a tight space. I went with the name brand because the lid stays put. The knockoffs don't. Thanks Blue Sea

Great Quality and fast shipping
This was a VERY good buy and really tight sturdy fuse highly recommended!!!! {UPDATE} After some time under the hood of my car the plastic or base of the block started braking apart like shattering away now allowing the block to slap around. Not good for anything outside of the cabin of vehicle.

Solid
I bought this to replace a block that came with two fuses stacked on top of each other. I didn't like that setup so I bought this one. This works great. My only complaint on this was that the holes for the screws were kind of small. I was using self tapping metal screws to mount this in a battery bay of an RV. The circumference of the self tapper up top was too big. I had to drill the plastic out of each side of the hole so I could get the screws to fit. Unfortunately, in AZ, these self tappers are all the same size on the top of the screw so I would have had to grind the screw down or drill the hole bigger on the plastic. I went with the plastic. Works good so far now that it is installed.

It’s a quality fuse holder. A bit on the expensive side but much better quality than the cheaper options

Seems good
Blue Sea Systems is generally considered to have quality products. This so far seems well made and suits the purpose. I won't care that the plastic top fails to stay attached, because I'll wrap some F4 tape around it.

the dimension between terminals.
The wrong Fuse Block Holder was delivered. Was incorrect to fit the longer ANL 35 fuse.
