    The snaps are durable. They look like they should last a long time!

    The stretch in the x-tendz is perfect for relieving stress and wear and tear of all the snaps. I personally used them on isenglass windshield and side curtains on a t-top and think they will extend the life of the covers.

    Mr Snappy’s products saved our camper canvas from ripping /damage in cold-weather camping. They blend seamlessly with the look of the camper, too. We couldn’t be more pleased with the quality, effectiveness and simplicity of our SNAP-X-TENDS, which exceeded our expectations. Highly, highly recommend!

    These really work well. I just “accidentaly” became aware of them while searching for snap extenders on Amazon. I was so pleased after trying them out, I placed a second order. For longer requirements, I use a “standard length” snap extender, then add a Mr. Snappy to make up the difference. With Mr. Snappy, you don’t need to have an exact length.

    As a result of the “standard” Mr. Snappy and the new “Super Snappy”? (which extends farther) I have been able to eliminate the need for “regular” fixed length snap extensions. In addtion, Mr. Snappy provides tension and helps keep my boat cover tight compaired to “exact length” extensions that never fit perfectly.
    Totally love and endorse Mr. Snappy.

    Excellent product that provided a simple fix to my unique problem: I needed to extend the length of the strap on pistol holster to fit a second pistol. One of these extenders worked perfectly… a $10 fix saved me the cost of buying a second holster,

    product worked exactly as I envisioned

    Price is a little steep but good product

    good product

  24. Richard Wilhelm

    Only suggestion is to offer straps with a longer end that is easier to grad hold of to unsnap maybe even with a finger loop.

    Worked great!


    Worked well for my application

    The Snap-X-Tendz bridged the gap between the factory Chaparral cockpit cover and the factory snaps on the hull. Chaparral failed to account for the aft facing jump seats so the factory cockpit cover didn’t fit properly. That’s poor quality control on Chaparral’s part and an opportunity for Mr. Snappy.

    Very happy with the quality and cost of the snaps, will tell all of our boating friends about Mr. Snappy!

  44. Joseph R.

    ordered 2 packs and received 1 free pack. very surprised seeing a free pack THANK YOU. We are on a Chaparral 270 and go out no matter the weather here in Florida. The original cockpit cover was destroyed last year during the last tropical storm so while a new top is being made we are using a “make shift” cover. We have 4 extenders on one snap, 2 on another and 1 on another. The extenders work PERFECTLY!!!!
