Monocular Telescope, 40X60 High Power HD Monocular with Smartphone Holder & Tripod, Waterproof Monocular with Durable and Clear FMC BAK4 Prism for Bird Watching, Camping, Hiking, Match - [2019 Newest]

Considering it’s a $20-30 item it’s pretty decent. Optical clarity is totally adequate for typical viewing but don’t expect it to rival an optic that cost 10x this much. Focus dial is easy to operate and the phone attachment seems to work as advertised but I don’t think it will accommodate a large phone like an iPhone plus model. The spring loaded jaws don’t want to open much beyond an iPhone X with case. The biggest disappointment in the package is the tripod, the slightest bump and the monocular wants to fall over. Needs a more substantial tripod. Overall it’s a solid performer considering the price.
