I am a big fan of Iwata, and pretty much have one of all their brushes at this point. Well, recently, because I am a clumsy oaf, I ding'd my needle on a painting and predictably it damaged the nozzle too. So I bought a few new needle/nozzle sets as I was nearly out. I had one spare, but no more. Well, I left my spare and went to use the new nozzles. The first - cup bubbles. Under a loupe, it had a V shaped hole on one side of the nozzle as if something had worn through that side. Annoying, but sometimes you get bad luck. The second, I got half way in with the little wrench, and using just a single finger to turn it, and it sheared right off near the top of the threads without going in further. I barely even felt it when it happened. So off to my old spare. 100% no problem, back in business. So I thought to maybe let Iwata know. I was kinda pissed I was out almost $200 in nozzles (micron nozzles are pricey), but able to keep working, so I could let that slide. But... if my local retailer was getting bad product, or there was an issue in the new run of nozzles, I figured I'd let Iwata know, as the quality control clearly had slipped. 30 years of no problems with Iwata parts, but then two in a row. Also the replacement needles were not properly sharp. That's less of an issue, as I sharpen and polish mine anyway. Factor finish is never great. So I dropped them a line with details, receipts, etc. I said in my message that wasn't expecting anything, but could they please look into the quality control of the nozzles, because I can't afford to have that happen again, and would hate to have to consider third party parts if this was an ongoing problem. So today they called me. An actual company customer service person called me up to apologize, and to send me two new complete fluid head systems to make up for it, and to put me in touch with a service tech to talk about what had happened. Attentive, helpful, and the service tech even offered to source a part for me in restoring a very, very old Iwata branded compressor that isn't quite what she once was. They are sending me a box to return the bad parts so they can inspect them, are checking to make sure that something didn't go wrong with a run, or someone ended up getting fakes and sending out more replacement parts than the actual bad parts. 10 years ago I had an Iwata compressor fail 5 years after purchase, and when I inquired about service, sight unseeen they sent me a replacement. Wow 5 years after purchase! Absolutely stellar service. So I just wanted to give Kudos to them, and relay a positive customer service story. When people ask me what I spend the extra money on Iwata stuff, it is this right here. They 100% stand by their products. In 30 years this is the first time I've had any issues with nozzles or fluid head parts, everything has always been top quality. But when something goes wrong, Iwata stand up to the plate. So, I tell you, it's worth the extra pennies. In the long run, if you paint every day, you will actually save money. So while I have a small army of various brushes from different companies, I keep coming back to my Iwatas.
