Question: Does it work with Canon T2i, T3i, & T4i DSLRs?
Document: 5D3- works great. I wish the pins for these tools were standard across all DSLR's (I had one for my T2i that wouldn't work with my 5D3 because the connector is different), but my wishing won't make it so. For what this does and for the price I don't what anyone else could want (except maybe an on/off switch).
I just plugged it in to see what it would do. I needed a cheap alternative to the branded canon version of the vanilla remote trigger and this one had some extra features that I have never used. I only use the single trigger button and the half press and full press work great, just as if you were pressing on the actual trigger on your camera.I use this with my Canon 5d Mark I.
Buil quality is good, looks very durable and just what I need for long exposures. Tested it once on my 5D MKiii and it worked! What else can I say. Absolutely no problems with seller, arrived on time, well protected in package. I bought one for my t2i from the same folks and it has worked flawlessly.
This remote timer is loaded with tools. It seems to work very well for remote release as well as timed release photographs.
Is a cheap material, buy work perfect. I recomend this for time lapse videos. Only is a little fragil. Good for the price.
The light on the lcd simply doesn't work. Apparently was 'not' checked before it was sent out. And given the price, it's not worth sending it back over. You get what you pay for.
it is very good remote witch works perfect. no on/off button which is really the only little doubt. you need to pull the batteries out after using which is fine for me an specialy for a price of 15 $Just let you know guys  - the timer is not 100% exactly in time and les then 1sek doesn't work. 100%  perfect for time laps, star traces and longtime exposures. Don' count on the 1/10
All the functions work on this camera. When you turn it on for the first time (i.e. insert batteries), make sure it is unplugged from the camera first. I initially thought it wasn't working when I plugged it in first and then inserted batteries and tried it out. Once I unplugged it and re-plugged it into the camera, it worked flawlessly in Bulb, Manual, and all other camera modes.Like others have pointed out, they should have included an on/off button. It can be a pain to remove and reinsert batteries all the time.
Often when I insert it, I don't get a proper connection and have to remove it and re-insert it. There are no bent pins in the camera (it's brand new and the port is visibly in excellent shape). I am able to get the unit to work, but once I do, it's remarkably difficult to remove. To be honest, I don't know if this is a flaw in the plug on the timer remote, or a design flaw in the port of the camera. If I get the chance to try other timers in the camera I will return and update this post.
Since such watches last quite a while with smaller batteries, I'm sure it will be fine but still strange. Fortunately, if the batteries do die and you don't have replacements, according to the manual, the shutter button will supposedly (I haven't tested it yet) continue to work with the camera. This is a very welcome feature for the times that I don't need the timer.Even with the strange little oddity aside, I would still recommend this product over a simple push-button one. You can't beat the price and it is well built.
