Today, I received the Metz 15 MS-1 twin flash with ring reflector. It's the first part of my macro setup, which hopefully will soon be joined by the 50mm Touit and a Metz 52 AF-1. My first impression was very positive - it's built much better than I anticipated, with a metal mount and a very tight plastic body. The menu is as simple as it could be, the servo mode works great and the recharge times are okay - can't really test it as the recharge time of the internal flash is much longer. The flash runs off 2 AAA batteries - I use Sanyo Eneloops. The light from the two GN15 flashes can be set from 1/1 to 1/32 and spread in a ratio of up to 1:8 between the two flashes. Both flashes feature a three-step reflector to direct the light. It also features a built-in focus assist light, which is a bright, white LED bulb. The "modeling light" works interesting: It fires through a full flash transistor charge in small, weak steps so that you get a few seconds of seeing how the light will look on the model. Here just a few OOC snapshots I just made: You can indeed achieve pretty flat light like with actual ring flashes if you desire. The following example is cropped and shot with a wide angle, non-macro lens, mind you. But at least you can see a little how the highlights in the eyes will look like from this flash. If you move away from the face more than a meter or so you'll just get a single highlight like with any other flash.
