I've tested these. We have a C.O. Bigelow nearby. They stopped selling Miller-Harris, but they still have a fair number of nice niche and hard-to-find fragrances. L'Artisan, CdG, Annick Goutal, several others.
The Barber Elixirs are at their store, and also at other storefronts from the same company. These include Bath & Body Works and something else that escapes me. The 4 color lines include colognes, aftershave balms, and other products. My favorite is the black, which supposedly uses agarwood or something that approximates it. That variant used to be very hard to find, but easier now. It has a medicinal, barbershop feel that my wife simply can't stand, but I like it. I also like the others - none are bad. The green is probably second with me. Somewhat pine-centered. Red is a bit spicy, but I don't recall how, and blue aquatic. All of them are very mild leanings, IMO - nothing like a REAL aquatic, green/pine, etc. They're pretty reasonably priced in the States. I did not really fall for any of them, but I wanted to own the black.
I think any of them is daywear suitable. The colognes are just that - colognes - lighter than EDTs. The aftershave balms are very light, too. I've worn both together and it is not as strong as a normal designer EdT + ASB. I think it's worth owning one, but I have no desire to own them all, even though they're very nicely priced, and (when they're on sale) one could own the full range for the price of many designer sets.
