I've pumped into someone hard and fast for 15-20 minutes straight before my arm started to get too tired (I could probably have gone a bit longer, especially with a short break, but the person I was using it on was about done by that point)In case anyone was wondering, I very much doubt this would be useful for anyone who wants to use the dildo on themselves - the angle is just way wrong. ### ⭐⭐⭐⭐⭐ Still Want to Argue ? *by A***R on 12 August 2017* Brilliant work out and a great weapon with a huge doc Johnson pull that bad boy out in the middle of any heated argument and it cuts the tension straight away!Still Want to Argue? ### ⭐⭐⭐⭐⭐ this knuckle duster ends all fights *by R***H on 14 October 2021* siswet approved ## Frequently Bought Together - Vac-U-Lock Knuckle Up - Black - Handheld Brass Knuckles-Style Grip for Vac-U-Lock Attachments, Non-Slip Grip, Body-Safe - by Doc Johnson - Doc Johnson Vac-U-Lock Platinum Luxe Harness with Plug – Black, Adjustable Unisex Comfort-Fit, O-Ring Compatible, Neoprene Design - Strap On Harness - for Adults Only - Vac-U-Lock CodeBlack 8 Inch Classic Dong - Black - Textured Veins, FIRMSKYN Material, Harness Compatible, Body-Safe - by Doc Johnson --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/87557284-vac-u-lock-knuckle-up-black-handheld-brass-knuckles-style](https://www.desertcart.pl/products/87557284-vac-u-lock-knuckle-up-black-handheld-brass-knuckles-style) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-28*
