The product appears to be well made but even with 8 new AA batteries it is only good for low light shooting. In addition, the modes, especially the flashing speed, are difficult to switch. If you have a pulsing setting that you need to SEE the speed of the flash, you will need to wait 3 seconds between speed changes. It's just a lengthy setup process. BUT once you get your settings right and use it in low light it will be a good product.
