TLDR: its has its flaws, but its generally pretty good. Make sure to lightly babysit until you've done a few runs consistently.
It's a rough bot, when it does work, it works pretty well.
The bot doesn't remember all the settings from previous sessions, so if you forget to change your food item, it'll stop. This should at least be a notification and a 5 min pause before stopping.
The most recent failure I had was "withdrawing: spade 1", which it did, and then just stopped and said "thanks for using the bot".
If using POH, you need to have runes at the time of starting the bot or be at your bank of choice because the bot is not intelligent enough and will not open the bank that is right in front of you to gather necessary traversal items. And for some reason, if you don't have the runes but have a ring of dueling, the bot will not use the ring of dueling (if your POH is your traversal method) without first casting home tele.
Occasionally in the tunnels it'll get stuck switching gear and thus won't pray even if being attacked (auto retaliate is turned off by the bot as well). If you die, the bot stops.
As I'm writing this, even though bolts are apart of my loadout, the bot did not withdraw them, I had to just manually run back to the bank just to get an item that is part of the loadout screen. This only happens with ammunition, does not happen if you use a blessing in my experience.
Referring back to the first line, when it does work, it works pretty well. I have gotten about 100 barrows KC over the course of a few sessions and noting the issues that come up along the way. I've only experienced a death twice, both times when not babysitting. When it doesn't get stuck switching armor in a doorway, it navigates the tunnels perfectly. It does a great job with 1-tick flicking prayer to maximize efficient use of prayer restores. I will continue to use the bot even with it's flaws because it generally does a good job.
