Quite the piece of equipment! Solidly made and well built

Quite the piece of equipment! Solidly made and well built. Easily the superior wrist roller

Worth all the money

I ordered this from Switzerland, I paid around 70 chf for shipping and around 40 chf for a handling fee (handling fee is cash only upon arrival).
It came in 5 - 6 days if I remember correctly.
The product feels very solid even by a touch and it's much lighter than I thought.
The level adjustment can go from the easiest where even weakest individual can have a workout up to level far beyond what I'm capable and I'm a decently strong guy.
This also improved my hand gripper strength capability a bit.
Worth every money and I'm taking this everywhere with me.
This is a very long-term investment in my strength

Its a Beast

Love the new SideWinder Xtreme T6 Forearm Exerciser. High quality build and the results are fantastic. It's not cheap in quality or price and anticipating many years of performance.

Gold Standard in forearm training!

Best product to train your forearms by far. The resistance is insane, the amount of grip variations is challenging. My forearms got at least 25% stronger and bigger after a month of using the T6.

BUY IT NOW!!! No seriously, go get one!

If you were already thinking of getting one, this is your sign. I own all types of wrist rollers, captains of crush grippers, adjustable grippers, gd iron 90s, gripedo's, buckets of sand, cut pieces of logs, eagle grips, judo/jiu jitsu grips for pull ups/cable attchments, iron mind forearm and grip developers... the list goes on. But the T6, for the price and versatility that it is, you can't go wrong. I'm not saying all the other stuff i own is no good but what i have in this one piece of equipment vs many, its worth every cent (penny).
The adjustable resistance, tapered thick bar, aggressive yet grippy knurling, everything in this sweet package is just brilliant. Humbled me very quickly upon first go but after using it for a solid week and a bit now, i'm managing to turn up the resistance and have seen my grip noticably sky rocket! Very happy with the purchase (after years of trying to get my hands on one living in Aus). If anyone else is living outside of the US, contact gripstrength and speak with Zane. Big shout out, customer service is top notch and goes above and beyond.
Would easily be 6,7,8 stars or more on the product, and service!
Do yourself a favour and add one into your grip training arsenal. Train anything, everything, all angles, in every wacky way you can. Nothing is ever wrong and just watch as your forearms go PopEye, wrists get thicker, vascularity is around 24/7. Nothing is ever too tight to undo or something you wont be able to overtighten by hand.
Best of luck fellow grip fiends!
