    Quality, smell, strength, euphoria. There is no better than C-Liquid. I recommend everyone

  2. milanovicante101

    Wow. This new relaxing fluid is a new modern thing to enjoy in the smoke. I like it.

  3. Giovani

    Miglior liquido in Europa… sito molto serio assistenza immediata
    Il mio ordine è partito il giorno stesso ed è arrivato il giorno successivo con 2 boccette in più
    Comprate da loro

  4. aewfefwfwq

    What a great buzz. I Love this stuff, its so easy to use, you can easily be puffing away in public getting baked of your head and no one knows nothing.

  5. sir-smokealot

    Great Product, worth a try esp if you get tested.

  6. thomas

    Pretty smooth and super relaxing blend. In my experience, it has been very euphoric, relaxing, and a bit trippy. I really like it.

  7. jackhackson

    It lasts long so I do not think I will be buying it again and again. Anyway, it is very strong and smooth at the same time so it is pretty good.

  8. DjJack92

    Great product. Super potent. I love it.

  9. Peter J

    I really love the scent and the good feelings it gives me. Fantastic vape liquid.

  10. Predrag

    I have been using flightams products for 5 years. This vape liquid is by far the best product I have found online. At first I was looking online for something that will help me sleep (I had a bad case insomnia). I tried several products with no luck but was extremely happy when I found this. I am using it every day, everywhere, like normal nicotine liquids. In my pub, when I go to cinema, etc… 1 month ago in Greece, I was using it on the beach for 10 days… you can imagine how my vacation was. Sometimes I am mixing it with a normal liquid for e-cigs if I want to tone it down (daily use for example). If you do your own research for these type of liquids, you will see the huge difference (in quality and price) between flightams and others. This is my GO TO place for vape liquids, for great taste, buzz and chill!

    Its fantastic,I noticed that it relaxes a lot and leads to mental calm

    But, instead of my regular order, I received a double order! I mean… not only the product is the best in Europe (I have tried liquids from different countries including UK), but service is also phenomenal.

    Flight AMS, you have got yourself a lifetime member for sure.

    The Truth, The Best

    I recently first tried a thc liquid from a local plug, long story short it was not as good as people had said.
    So I searched for something else after being let down and it led to this. I was hesitant to order at first but after persuading myself I should try I WILL NEVER GO BACK!!
    please order these because I swear to you this liquid is like no other, it will get you 5 star stoned.
    Also, I accidentally placed the order twice but after a couple emails with them a refund was set in place with out any complications, great service and were here sooner than expected

  132. Serkan Akyurek

  133. Steve V.

    Better then this is possible not more possible, and I mean that in a good way.
    But I feel as if they are ‘tempered down,’ compared to the Sloth Juice we could order a few years back.
    These C-liquids have a ‘brake’ in how much you can take, like some opiod medicine with an opiate-antagonist in it.
    But it’s still a more then descent enough high. At least, it is what you are looking for when you want to smoke weed but haven’t any.

    I would not recommend this for party’s, cause you might feel socially anxious, but in private, when you know everything is well and watch a good movie. (and nothing can go wrong)
    The taste of the liquid is very ‘glassy’ and after a period of use, you could say it refers to a crystal-like taste.
    Yes, Diamonds.

    Good stuff, next order is under way.

    FlightAMS is 100% Legit!!!
    I had my doubts when I first ordered from them whether or not i would get the desired products and how they would work. They came through on their promise and the product is by far the best that I have ever had! Black Diamond and mad hatter are both incredibly potent and provide a super chill high that won’t show up on the most commonly used tests. I highly recommend doing business with them and will be exclusively ordering from them in the future!

    I paid 200 € and the stuff got on hold and its been 2 weeks now did NOT get anything yet even the money they rejected to refund my money sooo watch out!!!!!!

  159. snake-eater100

    I made many orders at this guys. small orders and big orders, For more than a year I am ordering at them.
    Always went perfect… These guys have so many satisfied costumers and I can guarantee that the product is perfect.
    IT IS synthetic cannabinoids so of course you have to know how to handle it.
    But from all the SC I have ordered from the internet, this one is Far the BEST you can get.
    So if somebody did not get his order, I am sure it is not the fault or blame of FlightAms. They do their work perfect.
    In the corona months I was worried because a while you could not order. But now their back and back with a even more better formula.
    Thumbs up for FlightAms and keep up the good work.

    I just tried black diamond and man this stuff is very potent! I used a small squirt into about a half full vape tank. After about 2 hits I was DONE. The high was pretty intense! I was nearly in a trance just watching TV and snacking. This stuff if awesome. But be careful with it. It’s easy to become too high! But it’s great.. smells great, smooth but will knock your socks off. Lol great product. Good job flightams!!

    The product I ordered was only 5 mL which normally would last me a few hours but it ended up lasting about three days…i was so surprised how strong the liquid is, but it’s very pleasant effects seduce you into a magical wonderland, where it takes you down the rabbit hole with Alice. I absolutely love this product and will become a repeat customer for life. Thanks flight ams team for allowing me to become a lifelong customer…the effects were subtle at first, then quickly evolved into the walls melting around me, amazing…and i have had some of the best sleep experiences ever while using. Just be prepared, time will accelerate quicker, but you will wake refreshed. I believe this product deserve more than five stars, and i abbsolutely cant wait until my next order will shipp…im hoping for it anyday now.
