84/100Free full-size and batch downloads without login simplify the workflow; display ads and cropped fine hair are the trade-offs.

83/100Good hair handling and refinement tools are offset by login-gated downloads and HD credit costs; free previews do not imply full-size rights.

88/100Text and counts perform well with watermark-free exports using free credits; login is required, free results are public, and privacy and deletion require an upgrade.

75/100Login-free generation works, but the advertised model differs from the guest tier; free output is 640px, with about 85 seconds of waiting and a count error in this run.

89/100Free login-free 1248px clean downloads are not blocked by ads; video ads remain on the page and this result did not fully match requested object counts.
