Search their home page for links to applications for beta testers. Or simply Google keyword searches with the company’s name (like, say, “Google”) plus “hardware beta testers” and “application.” Find out how each company recruits their testers.  Many companies will offer online applications that you can submit right away. Some companies may then screen candidates through direct email or phone calls. The exact format to the application will vary from company to company. However, where appropriate, be sure to include any information that will make you stand out from other candidates. Do the same with any follow-up interviews or surveys that you may be asked to complete.  List all types of technology that you own and/or use frequently, such as phones, computers, other devices, and entertainment systems. Include personal info like age, gender, and location, since they may want to test certain products with specific demographics. Include your level of expertise with each one. For instance, if you can take a gaming console apart and put it back together again, say so. On the other hand, if you have no idea how one works but play them every so often, sell yourself as someone who could gauge how easily a product can be used by a novice. Again, the application process may differ from company to company. Expect follow-up surveys or interviews conducted by either the company itself or a second party that has been contracted to oversee their beta testing. Follow any directives about joining and participating in the company’s online community. Complete all necessary prerequisites to qualify for consideration. Be aware that fewer candidates are picked for hardware testing than with software testing. This is due to the fewer numbers of test units that the company can provide. Since there are more opportunities to test software, consider starting with that to gain a solid reputation and experience with the company.

Most guinea pigs should be able to keep themselves clean, but some long-haired guinea pigs may need to be bathed more often.  Bathing guinea pigs may increase their risks of becoming ill, as they become chilled easily.  Minimize this risk by keeping guinea pigs in warm towels until their fur is completely dry.  Attentive grooming and brushing can minimize your need to fully bathe your long-haired guinea pig.  You can brush your guinea pig with a soft-bristled baby brush.  You may also want to trim the hair around long-haired guinea pig's bottom to minimize how dirty the hair gets while your guinea pig uses the toilet.  If you feel that your guinea pig needs frequent baths, talk to your vet about weighing the risks of frequent bathing against the benefits of a cleaner guinea pig. Be sure to only use a shampoo that is specifically labeled as safe for guinea pigs.  Do not use human shampoo or dish detergent, as these may be too harsh and can cause skin irritation. Some specific shampoos that are safe to use are Scentsations Premium Small Animal Shampoo and Posh ‘n Go Protein Shampoo.

These kits contain 2 sets of strips that go on your upper and lower teeth. Go to your local pharmacy and check the tooth care section for whitening strips. Look for the American Dental Association seal of approval to demonstrate that this product is safe.  Read and follow all the instructions on any product you use. Currently, Crest whitening strips are the only brand that has ADA approval. Don’t buy any products that aren’t ADA-approved. Some whitening strips contain harsh chemicals that could damage your tooth enamel and irritate your gums. For a list of ADA-approved bleaching products, visit https://www.mouthhealthy.org/en/ada-seal-products/category-display?category=Bleaching+Products. This removes any buildup on your teeth that could block the whitening gel or stop the strips from sticking properly. Brush, floss, and rinse your teeth normally before attaching the strips. Not all whitening strips instruct you to brush your teeth first. Always check the instructions before you use them. Open your mouth and curl your lips back so you can see all your teeth. Peel the backing paper off one strip and press the sticky side down onto the front of your bottom teeth. Run your finger along the strip to make sure it sticks completely. If the strip sticks out above your teeth, fold that part over the top. Then do the same for your top teeth.  Most kits don’t have different strips for your top and bottom teeth, but double check anyway to make sure. Wash your hands before reaching into your mouth. The exact amount of time depends on how strong the whitening gel is, so leave them on for as long as the product instructs you to. While you wait, try lying back with your mouth slightly open so pull saliva away from your teeth.  Try to reduce the amount of times you swallow while the strips are attached. You might swallow some of the whitening chemicals, which could irritate your stomach. Don’t eat or drink while the strips are attached. Leave them in place and don’t touch or adjust them. After the correct amount of time has passed, reach into your mouth to the end of the strip and peel it off gently. Do the same for the other strip. Throw both of them away and don’t reuse them.  Leaving the strips on longer than instructed doesn’t increase the whitening affect. It only makes the chemicals irritate your teeth and gums. Make sure your hands are clean before reaching into your mouth. Wash them again if you’ve touched anything. Use water or a 50/50 water and mouthwash mixture. Swish the mixture around, focusing on the front of your teeth, to get any remaining gel off.  If you feel like more gel is stuck on your teeth, brush it off with your toothbrush and fluoride toothpaste. Removing the leftover gel is important because you could end up with white specks around your teeth if you leave the gel on in some spots. Different products have different instructions, ranging from twice a day for a week to once a day for 2 weeks. Double check the packaging and follow the treatment that you’re instructed to. If at any point your teeth feel overly sensitive or irritated, stop using the whitening strips. Contact your dentist and ask what you should do.
