My son had a Hudl2 until one day it decided to die. It had taken a charge, then switched off and never came back on. No hard reset methods work, and I suspect something went inside (it had been dropped and the casing partly opened).
Sadly Tesco don't make/sell them anymore so that's the end of that. Amazing piece of kit for the money and still to this day there's not really anything else out there with such a spec.
The Amazon Fire Kids certainly doesn't come close, but it DOES have access to apps/books/videos for free for a year, and I've just got one in the last few days to try. It's the 8GB version, and now they do it with 16GB, plus a card slot.
Most apps can be installed on the memory card but not all, so it is still possible to screw things up by running out of space as a result. No Android M combined storage option here.
Despite the low-res screen, the audio is nicely funnelled through the bumper style case and it's pretty nimble. The best thing by far is the parental controls, which is better than even how the Hudl2 managed things, which was quite basic in comparison.
Yes you can get the ordinary Fire 7 tablet, which is the same hardware, but there's no bumper case, no 2 year no-quibble warranty and you won't get a year of free kids apps/games/books.
I guess it's a case of waiting for when Amazon does a promo that knocks of £10-20 or so from time to time.
I'll be looking out for the next promo when I have to give my sample back to the PR company.
I do wish Amazon would bump up the specs a bit on their range. At least use 1280x800 on the entry level model and 1920x1080/1200 on the larger ones. I do think children would benefit as the books are going to be much easier to read.
