Quickly and easily attached to my grips and seat. They feel well made and have many flashing options.
Was pleasantly surprised that these feel much sturdier than expected for the price. Easily mounted to my handlebars and the rear light I actually attached to my helmet.
Front light ok, simple but adequate. Back light turns on but does not change functions, nor will it turn off without complete disassembly to remove the batteries.
These lights have been reliable and easy to use. Basic design and features and a very good price point.
