ipKonfig has posted a review on the Danger Den Maze4 P4 Water Blocks

Some features on waterblocks are for performance, some for looks, and some keep your options open. This offering from Danger Den seems to have been designed with all that in mind. Heavy duty quality assurance completes the package.

Owning a product from a company like Danger Den is much like owning a trophy, but unlike a trophy--you get to take it off the shelf and play with it. Its products are, in all respects, among the best looking and designed blocks on the market. It has always a pleasure to review the workmanship of one of its fine waterblocks. It has been in the water cooler business for some time now, offering safe and affordable water blocks for our processor cooling needs. So again we have an opportunity to have a look-see at its latest and greatest water block to hit the market: the Maze4. Mainly designed for the Intel Pentium 4 based processors, it comes in two flavors. First, the Pure-Poly topped block, and the CT (Copper Topped) water block. Both use the same internal Maze4 design, 1/2" fittings, and get the same pressure-tested quality check before shipping out-which makes for a good feeling once it arrives at your home/office.
