well I, My Dad, My Brother and my best friend has had one of these since 2017. We Record anything and everything, BUT we did notice we had to buy a cheap $30 HDMI switcher to bypass any HCDP. Thats so you can use your DVD, blu ray player hooked up to it, or any signal producing a HCDP signal. We all have those HDMI switchers installed, so we record ANYTHING we want, no matter what it is. I have about a 1 in 6 failure rate of a corrupt recording each to I try a long recording with it plus 90min, I have software that will correct the corrupted file. I find it easier to use fat32 with 2gb recorded files, more stable recordings and easier just to correct 1 - 2gb file than an entire 8 to 13gb single file using NTFS. I use a 128gb USB 3.0 Samsung flash drive. I have tried many of these and even though its not perfect its the most stable and trouble free on I have ever used. I only use it now 3-4x a year, but it works and records each time I need to. Its great when you buy a HD recording from Amazon prime and need a backup of it for your own records.
