The QUANTUM QL amplifiers in the ESX Portfolio are technically the small siblings of the QUANTUM QE models. Ideally, they can be used where the installation space is very tight. They are also emission-free and, like the large QE models, have the finest Class D technology on board, which leaves nothing to be desired in terms of performance, sound quality and setting options. The QL models are also coming with the space-saving remote control

LADIES this makes my long Hair feel much thicker and healthier. So NOT just for the Dudes.
Size: 16 Fl Oz (Pack of 1)
First off I am a woman and my Nephews were here for Christmas and tossed a bottle of the Bourbon Oak in the trash on the way out to head home. Well I wondered what it was and there was enough in it to try it for 2 weeks...LOL. So I did. OMG my Hair is thanking my Nephews for that. So I used that up and bought this one.
LOOK LADIES...yeah it isn't a Lady Scent but what it did for my long hair means I will keep buying this. I was using Viori for over a year and that is great stuff, cut down on my tangles in a big way. This CREMO made my Hair feel and really seem Thicker. as well as I have less fallout of hair. I would have to clean my brush daily. I have not pulled the hair from my brush since the day before Christmas. I still am in shock about that part. My Fine hair is long to the middle of my back, and gray or salt n pepper. I am not young anymore by a long shot, and Cremo has given my hair something it needed for years. I also find I do not have to wash my hair as often as I did before. I can go 4 days, when before it was 3 maximum. My hair has more moisture, is so much healthier, no greasiness at all. I wash once and leave it on for the time it takes to wash up the rest of me and rinse well. Follow up with Viori Conditioner just for the detangling. I think I don't really need the Viori as the backup but still use it.
OK the Scent is fine and not too strong, but it does last til I wash my hair again. Cremo don't change a thing.
I am thrilled with this brand of Shampoo/Conditioner. Oh Yeah.

Highly Recommend, Smells Amazing, Enjoyed by the both of us.
Size: 16 Fl Oz (Pack of 1)
I'm a woman and I'm obsessed with alll of the Cremo Italian Bergamot products that have come out recently! I got this for me, my husband and son. I just got the new hand soap! I'm getting ready to get the body spray for my 5th grader, who's getting into cologne and I have a perfume obsession so I'm having fun. My husband has this Cremo Italian Bergamot Body Wash too, and since I never know what he wants and put other products in, and this Cremo Italian Bergamot 2-1 Shampoo and conditioner is his main go to, because it runs out the most. I love it on my hair too! I really enjoy Bergamot as the opening scent in my favorite perfumes.
