We looked at several aspects when choosing the best testers, from objective measures such as physical dimensions and design to subjective considerations of look and feel. Though we have a variety of recommendations across various styles, all of our picks satisfy criteria that suit most people, thereby reducing the confusion of choice.
While you may find a tester for any aesthetic preference, we looked for testers that had simple, elegant designs - ones that would appeal to most people - rather than models that adhered to specific aesthetic choices.
Note: It doesn't mean that the testers that aren't mentioned here are bad. We picked these because these will help most of the people. If you have very specific preferences, we suggest you consider one of the below-mentioned products as a starting point before finalizing your pick.
