RingMaster large tire changer. Shares these same patterns with other similar internet-based new tools:
-Genuinely useful tool, if only for a small niche.
-Brought to market (often painfully) by experienced industry insiders, and not huge tool companies.
-Unpolished marketing that's a sign of genuineness. Kludgy mottos, gmail or yahoo company email addresses, homemade product videos.
