Very good product, fits comfortably in hand, easy to carry and store

Ok interval timer is plastic and light ... it looks like there's nothing in it ... but in the end, it's great practice, holds very well in hand, light, small (and therefore can be stored easily) .
It also serves as a simple remote control ... so this is a all in one.
Very simple to use and also plugs into the jack socket SLR (Canon), like the remote "classic".
For use, the seller sent by email leaflet in French.
And compared to other commercial products, it has an on / off button on the side of allowing so no need to switch off remove the batteries (there are 2 AAA formats).
Product recommend and buy if you are looking for this type of product, no need to buy the brand or spend more, this product is perfect for the Timelapse or simple programming picture (useful for astrophotography ).
