Unfortunately it is a Chinese knockoff I typically try to buy American when possible. there is nothing on the website regarding origin of manufacturing and got a run around when I called. Never trust a site that doesn't put an address on the website.

Canceled order never refunded More than a year ago, I placed an online order with Tnutz that, due to an unexpected emergency, I canceled by phone the same day. Although the person I talked to wasn't happy that I was canceling, he did cancel it. My payment was never refunded and the order was never shipped. Checking the order status on their website shows "Pending". I've left several messages and written to get this straightened out but they've ignored every attempt.

Slow processing Slow processing Made a few orders with them. Just with those few orders, I've seen many issues. Processing time for very small orders have taken longer than the 7 days they promise. I've also had multiple times where they sent me the wrong hardware and had to source hardware somewhere else at an additional cost to me. So that I can get my project done and not have to wait for them to respond and ship replacements. When addressing issues they have proven to be unresponsive at times. I just placed an order and 8 days later I'm finally getting a delivery date. I'm literally waiting on one piece to finish a project. One piece of profile takes half a month to get to a customer in the same time zone. This seems ridiculous to me. Even during these times. I've order other materials from other ecommerce sites, some on the other side of the country. Those came within the same week.

Processing time is 4x longer than… Processing time is 4x longer than stated on their website (took 19 days to ship my order). Of course they charged me the day I placed the order. Customer service is simply horrible. Once I FINALLY got my order it was was missing nearly 10% of the parts I ordered

Not honest about their turn around time… Not honest about their turn around time & terrible customer service. When I tried to get some help, I was given terrible attitude and was accused of "living under a rock". How these guys are still in business is beyond me. Avoid if at all possible !
