The Poly and Mojo combination is a powerful bit of hardware, but you need a case. The two fit snugly together, but I did not feel comfortable to walk around with them without a case keeping them fixed. So I ordered the case. At 95 euros it is not cheap. It also took a month to arrive at my doorstep. According to the retailer where I bought it, this was due to COVID-19. Oh well, in the end I got it.
