TRS Slider Review: Scheffler''s $90 Training Aid

I first saw the TRS Slider on Instagram. A guy in a simulator bay was strapped into what looked like a seatbelt, sliding his right arm around his body while his 7-iron made that sound — the one where you know the ball is going dead straight before you even look up. I thought, “there’s no way a $90 strap does that.”

Two weeks later, I was standing in my garage at 6 a.m., strapped into said seatbelt, and my wife asked if I was training for Dancing with the Stars. She wasn’t entirely wrong.

What It Is

The TRS Slider is an adjustable band that wraps around your chest and upper trail arm. It has a plastic slider mechanism (hence the name) that lets your arm move around your body but keeps it connected. Think of it as training wheels for your right elbow.

It comes in three sizes based on chest measurement: Small (30–36 inches), Medium (36–42), and Large (42–50). I’m a 40-inch chest and the Medium fit perfectly.

The whole thing weighs maybe six ounces. You unfold it, strap it on, adjust the slider tension, and swing. That’s the entire setup.

It was designed by Robert Rock, the guy with the prettiest swing on the European Tour, and Liam Bond, a 20-year tour veteran. More than 50 tour pros use it now, including the world #1. If Scheffler thinks it works, I’m willing to look stupid for a few weeks.

How It Feels To Use

The first swing is weird. Your trail arm wants to fly away from your body at the top of the backswing. That’s what it’s always done. The Slider says no. Not aggressively. It doesn’t lock your arm in place. It just sends a signal: “Hey, you’re disconnecting. Fix it.”

That slider mechanism is the clever part. Unlike the old David Leadbetter SwingLink from the ’90s (which was basically a rubber band that pinned your arm to your side), the TRS Slider lets your arm rotate and lift naturally. It guides, it doesn’t handcuff.

After 10 swings, I noticed two things. First, my backswing felt shorter but more controlled. Second, and more importantly, I could actually feel when my right elbow was in the right spot at impact. I’ve been playing for 15 years and I’ve never felt that before.

What It Fixed (And What It Didn’t)

My miss is a pull-hook. Club drops too far inside, hands flip to save it, and the ball starts left and keeps going left. It’s the classic over-the-top compensation pattern, and it’s killed more rounds than I can count.

After five range sessions with the Slider, roughly 10 minutes of warmup each time, my path straightened out. Not perfectly. I still hit the occasional pull. But the big hook that showed up once every six swings dropped to maybe once every 20. That’s real.

The Slider forces you to turn your body through impact instead of slinging your arms. When your trail arm stays connected, your chest has to rotate. When your chest rotates, the club follows the right path. It’s simple physics. It’s also the thing every lesson I’ve ever taken has tried to teach me, and the Slider made me feel it in 10 minutes.

What it doesn’t fix: grip issues, early extension, or alignment problems. If you’re aimed 20 yards right with a weak grip, strapping a band around your arm won’t save you. This is a swing path tool, not a magic wand.

The Skeptics Have a Point

Not everyone loves this thing. On GolfWRX, some sharp eyes pointed out that plenty of elite players swing with their trail elbow well off their body. They’re doing just fine. The “connected” swing is one model, not the only model.

They’re right. If you’re already striping it with a flying right elbow, don’t buy this. The Slider teaches a specific feel. If that feel doesn’t match your swing DNA, you’re going to hate it.

The other criticism: $90 is a lot for a strap. Also fair. You can buy two dozen Pro V1s for the same price, or a DownUnder Board 2.0 ($60–$90) if footwork is your problem, or a set of alignment sticks ($15) if you just need help aiming.

But alignment sticks don’t give you real-time feedback on your trail arm. The Slider does. Whether that’s worth $90 depends on what’s breaking your swing.

What Real Users Say

On TRS Golf’s site, the Slider sits at 4.8 out of 5 from more than 50,000 reviews. That’s either the best training aid in golf or some very happy marketing. On Amazon, where reviews are harder to game, it’s a more grounded 3.9 out of 5 across 64 reviews.

The common praise: “immediate feel,” “fixed my slice,” “finally understand connection.” The common complaint: sizing issues and the price. Luke Kerr-Dineen at Golf Digest called it a “checkpoint I come back to a couple times a month.” It’s useful, but not an everyday tool.

The Verdict

Buy it if you fight a slice or hook caused by disconnected arms. The trail-arm feedback is instant and the improvement transfers to the course faster than any swing thought ever will. The 60-day money-back guarantee takes the sting out of the $90 price tag.

Skip it if you already have a connected swing, or your problems are alignment, grip, or ground force. Get alignment sticks or a DownUnder Board instead.

Worth it if you’ve taken three lessons on “staying connected” and it still hasn’t clicked. Sometimes you need to feel it. This makes you feel it on swing one.

I’m keeping mine. Not because I look cool in it. I definitely don’t. But because the pull-hook that’s been living in my bag since 2019 finally moved out. $90 for a quieter golf brain is a bargain.\n
