"I ordered two masks plus filters. One mask and the filters arrived in 4 business days. The second mask was flagged on the website as a delayed delivery with a target date 3 weeks out. But I received a shipping notification today, only a week after ordering. So on the delivery side, VistaPrint appears to have fixed the problems reported on earlier reviews.
The mask itself has a good design. It has a contoured shape with a dart over the nose and a second panel under the across the bottom. This lets the mask fit high on your nose and curve down across your cheeks, and the bottom tucks under your chin, creating a good seal all around.
My only complaint is with the sizing. The website lists sizes as Child, Adult Small, and Adult Large. I'm a big guy and ordered the Adult Large. The packing list I received describes the mask as simply "Adult", and the nice retail packaging that the mask came in says "Size Adult". So either the Adult Large/Small sizing is a lie, or I was shipped the wrong item. I'm waiting to hear back from VistaPrint's customer service to find out which it is."
