The Steripod Clip-On Toothbrush Protector is a cap that covers a toothbrush to protect it from dirt, soap, or hair. It is useful when traveling and packing it in a bag. It is plastic, and the label states it is BPA free. It is meant to be thrown away after three months of use, so it contributes to the plastic trash that pollutes our environment. It would be better if this was made out of biodegradable materials, since it is meant to be thrown away after a short time. The package gives a phone number to get a three month reminder text to replace it, but I will not use that. The product was packaged in a disposable plastic bubble with a foil seal that had to be removed to open it. There was a strong scent that seemed like iodine after opening the package. The scent was so strong that I could smell it when I walked into another room. The package states that the product contains thymol. That is found in the herb thyme, which has been used for its antimicrobial properties. I liked that it used natural substances. There is a filter that is enclosed in the product, that contains the thymol, which depletes over time, so the product is meant to be replaced. The filter could not be removed from that small casing area; it may be possible to break it open, but the cap may be permanently broken after that. I did not attempt to do so. So, the whole cap has to be thrown away, once the thymol is no longer effective. The cap seemed to leave a bit of that strong thymol scent on my toothbrush head, because after I brushed my teeth, I could detect some of the thymol scent on my breath. The product clips around the head of a toothbrush to protect it. It has a metal coil to keep the two halves of the plastic cover together. I am concerned that the stronger metal, with repeated use, could break the thin plastic covers. The product has a hole in the bottom so the tooth brush handle may protrude through it. Dirt could, potentially, get through the hole. The product was large, so it moved around on the head of the toothbrush and was loose. I liked that it was clear, so that it is possible to see if it needs to be cleaned inside. If it is cleaned, there is a potential for water to get inside the filter casings, since there are tiny holes in it to release the thymol scent. That would, possibly, allow bacteria to get into that casing, which would defeat the purpose of the protective cover entirely. The Steripod is, overall, an adequate product, that could use some improvements.
