First remark, the product does not include 1.8m spiral cable as shown in the description. The cable provides straight and measure ten centimeters. Use corded is possible but much more limited than what suggests the announcement. The product is properly finished. The instructions (in English) is not more clear, but allows us to understand all the functions. Commissioning is very easy. I also specifies that the interval timer function has many a counter limited to 99 shots but can also be used in making unrestricted view: no problem therefore to make timelapse. I tested triggering 30m without problem, I have not tested more. I recommend this product.
