So who is looking for a good and cheap Funkauslöser, which I can only recommend this one. The Pixel RW-221 works with normal batteries (AAA). Alone that's a lot of value. It is super easy to connect and is easy to operate. Why I still only given 4 stars is because: Unfortunately, the article was not sent to the associated packaging, so I was first taken aback. I wanted a remote release for my Canon - but it was Nikon. So I had to call first. But it quickly became apparent that the packaging was merely wrong. A German manual one seeks in vain what due to the ease of use was not so bad though. So everything is half as dramatic. After first trying out all that was forgotten. A really good purchase!
