Are toy-grade RC helicopters worth buying?

Verified-purchase reviewers on Amazon give them decent ratings for casual indoor fun, but specialist communities on r/RCHeli and r/RCPlanes consistently warn that toy-grade helis (under roughly $50) typically last 'about 10 minutes of fun' before a crash breaks an unrepairable part. If the goal is a gift or office toy, they're fine; if the goal is learning the hobby, hobby-grade models from Blade or RC ERA are the consensus recommendation.
