Review: Excellent quality. Well designed and solid built - After having bought two of the cheaper ones on desertcart at 1/3 of the price of this, I finally decided to risk the £40 and see what it's like, intending to replace one of my existing fuse boxes. I am not disappointed. The quality of this unit shines through and I have immediately ordered another to replace the other cheap one.
Review: Excellent quality worth every penny - Used a couple of these now in different projects. Don’t think you can get anything better, these are top quality and work exactly as described!
