I can say for my part that the Sony HDR-AS15 does a really good job. I do not have the 179, - Euro paid and have to say though I for my first only a little over 100, - have paid for the Fahhrad and motorcycle package would be the good 70, - Euro would have been worth more definitely. Meanwhile, I have bought a second to and no problems. Of course there are the one or two points but we're not talking about an egg Wollmilchsau GoPro. The Full HD recordings are super. After updating to version 3.00 is even a Full HD recording at 60 frames per second are available. The installed image stabilizer swallows when switched a bit of quality but I say a verwackelungfreies HD video is always better than a shaky Full HD video. The slow motion shots are wonderful. As part of the update, although I would have desired a slower setting than 120 pictures, but this point may well one divorce the GoPro for themselves. The accessories I can also highly recommend. I have additionally brought me the surfboard holder. While I surf but not with tape, the Cam can be attached to other things without always equal to one of the Adhesive Mounts for use as excellent as well. The suction cup is absolutely super. She sucks not only sticks but on top of that. And the skeleton case is also an inevitable accessory. The fact that the Cam without an enclosure can not be mounted or lays. My opinion is: Although these Wollmilchsau lays no eggs but also costs half as much. If you are looking for a ActionCam and not even over 300 Euro loose but still a good quality brand equipment would then take has calmed it here. By long-construction may not be suitable for all areas of use, such as the cross variations but the best judge of the kan every man for himself. From me there gibts 5 star and I think I'll buy a third! :-)
