Cheap and gets the job done, however you get what you pay for.
The plug tester does not plug into TR plugs easily which is unfortunate because TR plugs are the standard nowadays. The light is bright!
Tic tester is a tad sensitive and requires holding onto the power button to operate, this is a huge con to me. Also the audible tone is rather lacking.
For DIYer and home owners it is a cheap toolset that works decently, for professionals look elsewhere.
