Would totally recommend the zippy inserts I got the kraken version, shipping was fast and even cam with a signed sticker. A1 service

I am still using the titanium handle cutouts and it the inserts make a noticeable difference, its a very neutral experience or in otherwords balanced basically perfect i love how they look as well

Perfect fit

I bought a couple mods so far from these guys and they're all great! They look amazing and don't change the flipping experience except for slightly muting the sounds a little, which I don't mind. I'll definitely be buying more products with more knives I own in the future!

Great blade inserts. The hydro cutouts are small, so these can be a little challenging to get in, but not bad. Zippy tutorial helped a lot. Also, using a medium thick guitar pick helped a lot with getting them perfectly flush. Aesthetically, the look is really cool, especially held up to light. The translucence makes it appear like it's glowing! Nice touch. Recommended

These really complete the hydro, and I love the way they noticably improve the feel in hand as well! The difference was instantly recognizable. And Zippy's legendary customer service is unmatched. I was so happy with the spacers, I ordered the flush spacers as well just to have variety. Thanks, Zippy!

Perfect!!! As always. Awesome product. Dont sleep on it.

Very snug fit, definitely staying put on the handles. They look great as well.

Love these on my superfly. Adds a beautiful splash of colour, and the fit and finish are great. The seller is also very helpful and responsive.

I was confused because I ordered through the shop app. If you’re going to buy these products do it from Zippy’s page on your internet browser so you can pick your color(s) & see exactly what you are paying for. It’s a good product that they sell.

I was absolutely the reason why the lucha mod had substantial pivot play. I sent my Lucha back to David after my review about being super happy and a little sad. I admit my hubris, and I failed to install four raceway washers in, thinking that the raceway washers were the washers with bearings. I completely failed to fill out four raceways worth of width on both my handles. I should have sent it back prior to writing a review. I swore to myself I watched it over and over enough to ensure I wasn't being stupid. But I was being stupid. And I'm sure when the Bali comes back I'm gonna be super pleased. This was a complete overlook on my behalf and I wish I could genuinely delete my initial review. Thank you David. I appreciate it so much man. You were timely about service and communication and you were super nice about my stupidity. I can't ask for any more than that level of service and integrity.

Update after receiving my Lucha after corrections:

I am so happy. I wish I could paste my email to big D after my Lucha came in again today, after my idiocy. I wish I could reiterate that this issue was my fault so much so that I hope my previous review is disregarded by future customers, and they see this one. I am night and day stoked. There is no more pivot play. At all. He warned me I may have damaged my blade cutouts by overtightening when I was thinking I had all of the hardware in. I don't intend to dismantle until I need to maintenance, but if I did damage it, he did well by making damn sure it doesn't even feel damaged, because I have zero pivot play now. It's perfect. I am to the moon. Tolerances are perfect on it. I sincerely can't even begin to describe how happy I am. And I wish I could take back my criticisms, because I will be the first one to admit that I did something wrong, and jumped the gun on filing a grievance. I'm mad at myself for it, but I couldn't be happier about what came to me today. Exceeded all my expectations and I'm ashamed that I couldn't follow directions well enough to have made this my primary review. Thank you D, I appreciate your time in fixing this, so much. I'm having so much fun flipping it. I could sincerely throw my stock Lucha handles in the trash and be content for the rest of time.

I'm not the best flipper yet, but I tried to show some pressure on the handles laterally to show tolerances, and a lil bit of flipping. I love the thing so much now. I must reiterate, I enjoyed the product before; I'm just trying to emphasize truly just how much it exceeds my expectations, and would have if I didn't make the mistakes I did when watching the assembly video.

I'm a neophyte; not very good.
The Zippy is quiet and nicely weighted.
I'm very pleased with it.
Build quality is incredibly solid.
Would purchase again.

A must have for sure!

It tasted good👍

Exactly what I ordered and way exceeded my expectations. I own a 3D printer but would not have been able to achieve this type of quality at my skill level. Would recommend to a friend and can see myself getting more in the future!
