Bests & Worsts Reviews from Amazon

This set of cedar shapes is economical. We've been using them for almost 2 years now - same ones. The cedar scent fades quickly, but that is no problem, because I buy pure cedar essential oil (the kind that goes in a essential oil diffuser) and put six drops of that on each block or sachet bag to "recharge". I don't bother with sanding them. No need. Essential oil of cedar is one of the lesser expensive oils out there. I will allow the cedar essential oil to soak into the wood shapes/sachetss for an hour and then put them back where they were. The dresser drawers, closets, storage totes, cars will then smell noticeably of cedar for months. No longer have moths or spiders in the closets. Just be aware, cedar wood, even fresh cut, eventually fades over time, and has to be replenished with cedar oil. Cedar oil will wash out of most fabrics, except maybe for silk or chiffon. If that is an issue, put the cedar block in a pantyhose stocking or mesh bag to store with things such as silk scarves. The cedar shavings sachets are used in our cars. Those too get replenished with cedar EO and work excellent. This set would make a wonderful gift if you include a bottle of essential cedar oil with it (Amazon sells it). I prefer to not use a cedar oil spray, because I find that several drops of the cedar oil lasts way longer and goes directly onto/into the wood and not the air as a spray does. Oh, and just because you cannot smell the cedar blocks when they have faded, does not mean insects or rodents with much more sensitive smell cannot.
