I had a booster from the original batch, the first week they were listed in the uk.
That broke after the first 3 days (same issue with the base coming apart).
Artisan sent me a new one out, after I emailed them.
I sent a photo of it attached to the mail, and the new ones fine so far.
I have another booster I recently acquired in the yo-yo, and yes, after 3 days, it's broken!
Again another email, and yet another replacement needs sending

You'd think that for the price, they would engineer something a bit more refined and road tested.
