Function very well, manufacturing quality mediocre

About the general function of this trigger you actually need no more words to lose: They are all highly praised and recommended in almost every relevant book (eg by Thilo Gockel) or blog (eg Krolop / Gerst). In particular, they are of course extremely inexpensive in comparison to the top dog of Pocketwizzard.
Slightly disappointed I am, however, of the manufacturing quality: My AAA batteries slip with regularity in the battery compartment so that the trigger typically just will not work if it fluctuates on extended flash tripod at the top in front of him. Of course you can make do with as a piece of foam or sponge rubber, but that should not really be necessary, because slightly lower production tolerances have the parts not made substantially more expensive.
Caution incidentally before Super cheap offers from China: As I have already waited 6 weeks and then had to return to handle the purchase through Amazon. For a little bit more and in a well-reputed suppliers that is not a problem.
