WHAT THEY THINK ABOUT OUR PLUNGERS

It’s a real pleasure to shoot with the points and the Micro from Wooooojack. The quality and precision of their products give me complete confidence in my equipment.

Wooooojack products have truly impressed me, whether it’s the Revo, the Micro, or the Primo! The quality is outstanding, and you can tell every detail has been carefully designed. They are extremely consistent, shot after shot, they remain precise and reliable. The Micro operates with ultra-smoothness, everything feels natural. Adjustments are surprisingly easy, make a tweak, and it’s perfect. In short, top-of-the-line equipment that really inspires confidence on the shooting line!

The adjustment tolerances of the Micro plunger are truly excellent. This model is outstanding, and I recommend it without hesitation. In my opinion, it’s the best on the market in the category of plungers without micrometric center-shot adjustment. On top of that, it’s offered at an excellent price!

I was particularly impressed by your Revo plunger. It addresses a common issue for Barebow archers in the United States: having to switch arrows depending on the discipline (indoor, 50m outdoor, field, or 3D) and adjust the center shot accordingly. Your innovation brings real ease of use and opens up new possibilities for Barebow practice.

In my opinion, the Revo is currently the best plunger a barebow archer can use.

I’ve been using the Revo for two years, and I’ve never had the slightest issue. It’s very easy to adjust and allows you to quickly correct lateral alignment without having to take everything apart. The product quality is excellent, as is the customer service. I highly recommend it!

The Revo plunger is perfect for easily changing setups. I can adjust it in no time, and the micrometric center-shot adjustment has been a game changer for me!

I’ve been using the Revo since its launch and have set all my personal records with it. I particularly appreciate how easy it is to adjust. I recommend it without hesitation!

The Revo is the most advanced plunger I’ve ever used. It’s by far the easiest to adjust and offers unmatched precision. I’ve set all my personal records with this plunger, and it has been with me for several years, even helping me win a World Cup stage. I highly recommend it!
