This sync light is very cheap and obviously cheaply made to sell cheap. Like I said, it actually works VERY well! I have tested its accuracy with an expensive timepiece intended for everyday use by a mechanic and its dial matches the more expensive one perfectly. The expensive time display has a brighter flash, but it's enough to get the job done. As often as I need to use it (rarely), this sync light will do what I need. This is a great buy for the money. FYI, the dial type preset is easier to use than the digital type preset found on some much more expensive timing tubes. Don't waste your money on a digital guy.
