According to what I’ve been told in the past from @AnkerOfficial, power user samples are released according to market demands, stock availability as well as product manager’s decisions. So options for each of the territories (US, UK, DE, IT etc) can be both the same and different at any given time. There is also no set schedule when items are offered to members…
Hope this helps 
Thank you!
Makes sense as it’s not being pushed as a ‘Anker’ product, never seen a Robovac on the PU page before or since it hit the UK…
I bet anonymous backers were not considered 
Is this open to Canadian testers too? I have been a member since 2015 and have reviewed a sample before, but there are no available sample options on my power user page.
Every month there will be a new update for the available sample so just keep an eye out for it!
Missed out on a SoundCore 2 today. Gutted I didn’t check sooner 
Also, being offered screen protectors and cases for an iPhone X. My profile says I have an iPhone 7 Plus. Why can’t I be offered cases for my device?
I’d love a Karapax Breeze for my phone but can’t buy them
either yet 
Weird, not showing anything on mine apart from my submitted ‘Curves’ and my past submissions. Surprised the Curve’s review has not been added to the list rather than being at the top 
You are probably on the (Send them the best stuff) list 
Hey Im finally a power user member 
My phone is listed as a Samsung and the same I just see cases for the iPhone x…kinda makes me want one now haha
Congrats and welcome to the club
Congratulations 
Great feeling 
I’m the same. Gutted I’m in the middle of my contract. I do want that phone
Welcome Back 
There was Eufy Genius, which is now completely through email.
For the Nebula, they had to fill out a Google Form to apply.
Forgot about the Eufy Genius…
For the Nebula I was referring the lack of ‘anonymous backers’ on the chosen list, if you can’t put someones name down as an alpha tester, it would rule out the anonymous backers as candidates…
How long does it take for new samples to appear in my PU tab after I submitted my review?
It all depends on the market/area/ and if they have stock of items. It varies for everyone
Maybe you can check it every week, products update in Europe will be slower generally.
I tend to check every morning around 8h30, and a second time around 10 am.
Day in, Day out. I have missed 1 or 2 products that I didn’t need etc and I wouldn’t mind seeing Sample Claimed every day/week if someone got on there quickly but seeing nothing is a shame.
