    I am taking time to let you know the ear plugs work very well when working around heavy equipment and blowing down gas lines. The sound is very minor compared to the regular ear plugs, easy to put in and very comfortable. I am very happy with them; they stay with me all the time in the case you gave me. I did test them out on different situation and they work well.
    Thanks & good work.

    It’s been two weeks now that I have used the hearing protection I got at End of Trail. While I have taken some ribbing about the color–pink–I have also gotten quite a few inquiries about their effectiveness and comfort. I can tell you that in both categories I have responded in the assertive positive. I am quite happy with the plugs and look forward to the permanent pair I ordered.
    Many Thanks!

    I tried out the custom ear plugs you made me on the 4th at the gun show. They are excellant and more comfy than foam ear plugs! Thanks alot!

    Just had a chance to try out my new ear plugs yesterday. People noticed them right away and have been very interested in getting a pair. I told them we are trying to get the plant to buy them for all.

    I wore mine throughout my 12-hour shift without any discomfort. However, it was a little more difficult to hear my co-workers as the protection was so good, but I could still hear my radio and still communicate with others. I just had to ask them to repeat themselves.

    Have a great weekend! And thanks again for protecting my hearing!

    I have returned to work, and I do use my new earplugs on a daily basis. I love them; they are so comfortable I often forget they are in. I really hope to have all of my co-workers share in this experience. Last I spoke with a coworker she said she was going to our new safety manager about your products.

    Thank you!

    The ear plugs are amazing; the ringing stopped in both of my ears. I put them in on a job site and boom all I can hear is myself chewing gum. Thank you so much.

    Noise is a Low Volume at 100mph!
    I purchased a set of on-site protectors to use when riding my motorcycle. Due to the way my helmet contacts my ear, it broke the seal on my left ear, so it was not fully protecting me. I contacted Mark and he said to see him at the next show where we made a new plug and let it set up while I wore the helmet. Total success! I have been riding since 1965, starting with a Triumph Bonneville through various sport and touring bikes, and it has never been this pleasant. Even with the helmet directly in the wind stream at 100mph, the noise is muted to a low volume. I can still hear other vehicles’ tires, horns, or sirens, so it is safe. Mark is friendly, knowledgeable, professional and stands behind his work. Thanks again, Mark!

    Hello Mark,

    I am a Cowboy Action shooter with SASS.

    I had you make me custom molded earplugs at EOT about 5 years ago.

    I must tell you that they have been GREAT! They have held up for hundreds of shooting sessions. They have held their shape and continue to meet any and all my expectations.

    Thank you very much for doing this and coming out to our World Championship to provide an excellent product in a convenient manner.

    These new earpieces I got at the NM State Championship work great.
    Much better than the foam plugs I have used for years.
    I wish I would have got some a long time ago.
    They feel great in the ear.

    I am the person who won a pair of your ear plugs. Best pair I have ever worn, used all week in work shop and had no pain from them my ears. Best thing I ever won.
    Thanks so much

    Well, Mark made me custom ear protection at the Rocky Mountain Regional IDPA shoot in Cameo Colorado (cameosec.org) today. And I can tell you that as a professional photographer and am around shooting very often they are a godsend and I have only wore them for a few hours. I did not feel like they were going to come out or get loose, I did not have to keep re-adjusting them and the best part is my ears don’t ring.
