Review on Cygolite Hypershot 350 Lumen Bike Tail Light with 7 Night and Daytime Modes, User Adjustable Flash Speeds, Compact and Durable Design, IP64 Water Resistance, Secured Hard Mount, USB Rechargeable, Ideal for Busy Streets by Logan Tripp

GOOD - Super bright, definitely bright enough for daytime security - Lots of modes let you choose what it should do and how long it lasts on a charge - The mount is good, you can remove it easily, but it doesn't fall off. Seems to be very waterproof and durable. Two-button operation makes it easy to operate without memorizing modes or searching through them to find what you want. Cygolite: good brand, good support. They replace the USB rubber cover when it wears out over time. Uses standard USB charging so you can have a charging cable if you need a longer one or something similar. Can be put on backpack or bag. It doesn't have to be on the bike or bundled with the mount. If you lock your bike to a public rack, you can put the light in your bag, coat or pocket so you don't forget it on your bike and some bad guy gets away with it. POOR - uses USB micro for charging, this type of connector is directional and prone to corrosion and contamination. It will probably be fine, but USB-C is better. If you don't remove it from a public bike rack, it could be stolen. No problem with the light itself, just keep that in mind. - Quite expensive but in my experience this brand lasts a long time - the USB rubber cover wears out and falls off. You will replace it, but you have to deal with it.
