Bought a $15 clip on phone lens off a gas station rack in Tulsa, total junk, save your cash
The thing fell apart after 3 uses and the pics looked like they came from a 2007 flip phone. My real tip if you want cheap weird lens fun is thrift stores, got a working 2x tele off a bin in Tulsa for $3. What junk gear did you overpay for at a checkout counter?
My old roommate bought a 4 pack of those sticky lens things at a CVS in Amarillo and one popped off into a creek the first day. Thrift bins are where it's at, half my camera junk came from a Goodwill in Waco.
