I bought a Pilo 2 fabric shaver and like it, but don't love it.
Pros - It's a really nice design, easy to hold and relatively straightforward to use. After a little work greatly improves the appearance of fabrics. My partner has a woolen hat which was looking really rough, and now looks like new.
On the negative side, the Pilo 2 is hugely expensive compared to reasonably similar fabric shavers. For example there's a Philips model for example which is a third of the price which seems to have pretty good reviews, and costs a 3rd of the price.
I also had some issues getting it to work when I first started using it. It would run for 30 seconds and then slowly grind to a halt despite the fact I'd charged it.
Also, the Pilo 2 loses a review star for the fact that even though it comes with a USB-C charging port, you can't actually charge it with a true USB-C cable, but only a USB-C to USB-A cable. This is lazy engineering in my view, and does not future-proof this product.
My verdict is I'll keep it now I have it, but next time I'll probably buy a cheaper model.
