    Nice flag except the stitching on the lower corner came undone and is allowing the fold to come undone. Happened after a week. Going to try and stitch or glue it together.

Durable but fades badly. :-(

"Initially, the flag was beautiful and felt sturdy and well constructed with a nice fabric weight. Physically, the flag has held up well but after only 3 months the flag is severely faded. I would not buy this flag again for outdoor use."

— Kent A. (2/5)

Lasted only two months

"It's been windy here, but this flag started tearing within two months of flying. Disappointed, to say the least. I ordered and purchased two of these. I think they should send me a replacement flag(free of charge), for the price that I paid. I could have shopped elsewhere."

— William A. (3/5)

Never Again

"The first Koralex 4x6 flag lasted 6 days before shredding horribly. They sen a replacement per warranty and this flag lasted 10 days before unraveling. I cannot recommend products from this company."

— Scott B. (1/5)

Great company service selling a great product

WOW! Torn and shredded in less than 3 months.

"Wanted a USA made flag. Thought pricing was fair for the flag. I've had cheaper flags last twice as long. Will deal with other USA manufactured regardless of cost."

"My flags will go up after the holidays when my Christmas decor comes down off of my pole. My true review will be after flying it for 6+ months. As of now, the flags I ordered look good, ordering was easy, and purchasing USA produced and owned is a must."
