HIGHLY RECOMMENDED. Spells great
I use this product everyday and have used an entire set. They smell great and get you clean, there is a loofa bag included where you put the soap inside and makes scrubbing convenient. Recommend if you want to feel clean and smell really good.. this is the set you can use. I know the ladies like it a lot. I get compliments all the time. One lady told me "You smell like money"... LOL.. true story.

Great scent, but leaves a film on my skin.
I was expecting bars of soap with more of a peppermint/eucalyptus fragrance and I just could not relate those fragrances to what the soap actually smells like. The Viking Revolution soap doesn't smell bad per se, and actually for me is rather fragrance neutral like you might find with the more sterile hospital and clinic type soaps. The lather factor for the Viking Revolution soap is mild to moderate in our hard water. It doesn't overdo lathering up but does lather up enough to let you know it is soap and is rather pleasing when rinsing it off where with some soaps you rinse and rinse and still need to rinse more to get the lather off your skin. I wash my hands and face many times throughout the day and night and so far the Viking Revolution soap has done a great job in leaving me feel a bit more refreshed and clean. I have noticed a bit of moisturizing of my face and hands being much softer after use, so the Viking Revolution soap does seem to come through with that feature. I handle and am around livestock and animals quite often and did notice that the soap seemed to cut through the grime pretty easily. I haven't tried the Viking Revolution as a body wash type soap. The square bars are just about a perfect fit for my hand and are easy to hold onto. I will use one bar for the shower and keep the bar in a drip rack where it has a chance to dry out after use. I do really like the presentation of the soap itself and it's a nice touch that each bar comes individually wrapped and includes a sticker and a small card. A rather attractive package if you are giving it for a gift. I'm more favorable of recommending this soap than not recommending it. The only reason I am giving 4 stars is for the fragrances not really being detectable as peppermint and eucalyptus.I do think I would buy this soap again though, fragrance or not.

Awesome soap!
I love this soap. It was a little small, ut was great quality. If smelled good and did not break me out. I have very sensitive skin and this was very gentle on my skin. I usually use caswell and Massey soap and this soap is every bit as good as my normal c&m soap. Very good soap. I Will definitely will buy again.

Scent is too perfumey
This soap pack is ok for the price, but the bars don't lather very well. They do have a good level of moisturizer that doesn't feel too oily, but my big complaint is the scents. The black one is ok, but the others are like cheap perfume. And I mean CHEAP perfume. It actually hurts my nose. I have used higher end soaps with a beautiful scent that is subtle and natural. This is not that. Overall not a bad product for the price, but don't expect to smell like a $1 perfume. Yuck

Great scents and clean feel.”
This 4-pack (Sandalwood Amber, Mint Olive, Turmeric Citrus, Activated Charcoal) hits the mark. Natural, handmade, and leaves skin feeling fresh without drying out.
