I was thinking about buying something better than Canon RS-80N3. Canon's TC80N3 is the only choice I was able to find and it is insanely expensive. Recently I found out that there is alternative available for 1/3 of the price. After reading review on Amazon I decided to give it a try.
When I unpacked unit it looked quite solid. Screen is quite big in comparison to TC80N3. First glitch was a connector, it did not click as easily as Canon's. Frankly I was not sure if it's save to push it hard. I did not want to damage pins on camera connector. It never seem to be pushed down entirely but apparently it does not matter. It works anyway. After this initial problem I was trying how it would work for time lapse video shooting. There is no big manual required. Reading instructions on single piece of paper once is enough to operate it. It does the job. I was not able to check all functions but I like what I have seen so far. I am not throwing away my old remote yet cause I want to check new one in more extreme weather conditions.
