Ok when on sale
I usually use Viovio for books, but one time sent a book to Winkflash that I had already done at Viovio, because they had a big sale (was it 35%?) and I wanted to compare. Print and color quality were fine, speed and shipping were fine. However, the full color hard cover looked and felt cheap, the surface having a bit of "bubble" around the outer edges seemingly not glued down. No way to create a wrap around cover. Not bad for the price, but at full price, Viovio quality is obviously better.
