I got this for adjusting guitars at home so I needed something I could easily put away in a drawer. This product + a towel = portable work bench. It obviously won't be a perfect fit for all necks (like 5-string basses) but works great for most guitars and 4-string basses. It sits nicely on the surface and won't slide around.
The built in bag is a nice touch. There's enough room for most essential guitar adjustment tools.
The price... well, it's not expensive but almost 20 Euro for a small piece of plastic is a bit steep in my opinion. I guess there's a 10 Euro upcharge for the Fender logo...
Still, it's a decent product that makes adjusting your guitar a bit easier. Would I buy it again? Yes, probably, unless I could find something similar at a lower price.
