A few people on the babywearer said that these seemed to be constructed safely, but many mamas have been upset by this product because the design of this mei tai is almost an exact copy of another mei tai brand, not to mention it being made by Infantino who manufactures the awful bag slings.
And IMO, bag slings make for unsafe carriers no matter how they are used. The design of bag slings makes it extemely difficult, if not impossible to wear baby in what most sling experts would consider a safe manner. They are designed to only be used in a cradle carry, and with the elastic at the top, the bag naturally curves into a "C" position, which makes it hard for most babies to keep their chin away from their chest, and to keep babies face uncovered by the carrier's fabric.
