Undecided, I recommend a visit to the manufacturer's site [...] here you can download the English manual and study the individual functions. The other products are quite interesting.
The device has a two-stage release button (Focusing & trigger) and a scratch-resistant, backlit display. It has the following settings: Single trip, multi-second increments timer, bulb initiation and two timeout settings. The Bulb function enables long exposure - without - that must be kept pressed the shutter button. You press once to open and a second time to close.
I really missing is an additional IR function. Therefore, for easy work I bought additionally for the 10 Aputure Combo IR and cable release CR3N. This has a simple trip function, a small housing and a short cable - which is interchangeable with the pixels of the TC-252! - And IR. In general, the possibility is to replace the cable very important, I think. So the device can survive for several years, and cameras.
