Product is pretty much identical to the Canon TC-80N3 (mine is about 7 years old), differing only in the setting wheel not rotating but acting like an up/down switch, and not having a locking connector. Actually, the Aputure's setting wheel is more intuitive than the Canon in that the numbers being set increase as the wheel is moved up, whereas the Canon very non-intuitively decreases.
My only complaint is that the button batteries supplied with the intervalometer all died within a few weeks. I have yet to buy new batteries to find out if the cause is poor quality batteries, or if the intervalometer drains them. This happened to all 3 of the Aputure intervalometers I purchased. The Canon intervalometer I have still goes for years on the same battery.
