Have the SJ1000 acquired to put it in an extreme outdoor week in Oetztal early 2014. The price of a GoPro was beyond my budget for the Action holidays. Helpful for the purchase decision were diverse, detailed YouTube videos over and with the camera, all spoke in glowing terms of the SJ1000. After a short delivery time and the first assessment already had the impression that hardware quality and accessories seemed to be super. First native tests in various Einsatzmodi were a few exceptions impressively well. Therefore, I will mention only the use of the bicycle handlebar as unusable because the handlebar adapter so many vibrations in the Cam transmits that the HD image is too much to bear. Otherwise, all test shots were even underwater or in very low light just good to excellent. After use in climbing, rafting, canoe, paragliding and canyoning was clear to me: "Everything done right!" Even the direct comparison of the recordings with the recordings of several GoPros the same outdoor event was objectively better HD pictures of SJ1000. The battery life were consistently 120 to 150 min. Now the small fly in the ointment: The plastic quality of the accessories / adapter is not the best. Here the GoPro accessories is a clear advantage. The material is simply quality. But now the seller's service. My material had suffered greatly in the mentioned outdoor use and so I had the idea, but simply times to ask the seller for replacement. My request in this regard has been answered very quickly and after a short correspondence to me a complete new set of accessories has been sent free of charge. It lacked only the camera but that does their service also still unabated great. Was of this service and I am thrilled. Conclusion: Absolute buy recommendation of Qumox SJ1000 (then Ramozz SJ1000). Anhängend still an example of two "snapshots" of a HD video of SJ1000
