Ok quality - the steel is seamed tube that looks like it has clear coat on it - this unfortunately clogs the knurling. The welds are ok - serviceable but not pretty. The loading pin although linished on the threaded end is still awkward to thread into the mace handle - to be fair someone else mentioned this in a you tube review - he wasn’t too concerned but then he would have paid a lot less as he was a domestic customer.
If you are buying one from the uk you get properly stung - £80 post and another £80+ duties (this is made clear on the site). Probably an acceptable item if you’re buying in the USA but in Europe? - I would wait till Rogue fitness start making these they will do a better job.
