STL: most-reported complaints

Automated analysis of 247 public Trustpilot reviews published 2014-02-20 to 2026-09-01. TrustScore 4.9 from 2,517 total reviews — see the Trustpilot page. Quick answer: is STL legit? Issues below reflect what reviewers reported, not findings of wrongdoing.

Reviewers most often report issues categorized as 'Other,' accounting for 60% of the 20 identified complaints, with specific mentions of a lack of flexibility, misinformation, and disappointing service. A further 25% of complaints relate to services not being as described, such as workshops that reviewers felt were lacking in content despite their high cost. The remaining 15% of complaints cite poor core service, including instances of rude behavior. No clear trend can be established for these issues due to the limited number of reviews.

Trends are computed from dated review counts only. Negative reviews are deliberately over-sampled for evidence depth; headline percentages use an unbiased recent sample only.
