I've been using a Oneway Stronghold chuck for years now. It started loosening up on its own. I contacted OneWay and they offered to send a replacement with no strings attached other than I have to send the old one back. as promised, my new chuck showed up today witha return label. Just want to give them a big thanks for their fantastic customer service. They will now be on the top of my list when it comes to Lathes, Chucks and anything else they may offer. I'ma happy guy today
