Unfortuntely this unit can't consistently count down the time to the next shot.For example: If you set a Delay of 0s, and interval of 10s, what you get is an immediate first shot, followed by a 10s interval (as expected), then the second shot, then a 9 second interval, then the next shot, then another 9 second interval etc. etc. until the programmed number of shots is reached.You therefore could add one second to the interval to get what you actually need, but the first interval will then be too long.Watching the display you can see the first countdown 'second' is skipped really quickly and only the subsequent seconds are accurate. Something is wrong with the electronics inside or the internal programming of the unit.Edit: The vendor has offered to refund my money if I remove my review. Absolutely disgraceful. See below from their email:hello friendwe have seen you leave one negative feedback for our this goods, we think you may not familar with our this goods.could we refund you full money and you agree remove this reviews from ths listing ?this is have bad effect for our business for new brand growth, hope u can help us.THankBest regardschristy

Been trying it out all morning on my 6D and there's a couple of things i think. Firstly when you set the delay - that works a treat. When you set the long exposure - it's up to 2-3 seconds out on the timer. The interval as well as the delay works perfectly, What i mean is the focus has locked on within the say 3 seconds delay but it can run up to 2-3 seconds before it opens the shutter (hear it on camera) although the screen says it's already started, Found this rather annoying at first but now i'm aware of it then i just need to remember to add them seconds on. I bought this for astro photography and this may prove a problem and will need a number of test shots else i'll be setting it up correctly but getting movement in the star trails. Perhaps they are all like this? I don't know first programmable one i've bought.The other thing is the buttons i can't decide if they feel clunkly well made or clunkly cheap.Overall i see this has great potential for time lapses especially but if the inconsistent shutter opening proves hard to do astro then it may have to lose a star,

Does exactly what it is meant to, I have used intervalometer son all my cameras and I bought this as a back up for my 7dmkii, despite it having a built in intervalometer in the camera it is always ideal to have a back up and for this price well worth it.

Great having LCD screen whether it's for single or multi shooting. Took a few goes before it became obvious for the sequence, but, that was me rather than equipment..

This product is very good value for money. It took me a while to understand the setup but when I did it worked great.
