I would just emphasise that the general rule is that you get what you pay for. We started out “cheap” just to have a quick look see what was going on and bought Crenova. We have had three now and had issues with all of them. I should say we only bought one, two were replacements, they are very good at replacing them with “new” models but they are unreliable.
We then went for a Browning, around x3 the price of a Crenova but it just does what is says it will do. So far very reliable and good quality stills and videos and sound.
They are available from Nature Spy, there is a link on here, who offer very good service.
