Shipping, packaging, and unboxing experience
The TRS Golf website is simple and easy to use. I like that they show tour professionals like Rory McIlroy, Tommy Fleetwood and Viktor Hovland using their product. Seeing the best players in the world using the TRS Slider can give you confidence that it’s a good product, and it also shows you how their swings look whilst using it, which is useful for comparison when looking at your own swing.
I found the ordering process to be very simple. For anybody looking to order the Slider after reading this review, be sure to follow their sizing advice carefully. I initially ordered a small one, and whilst it did fit me, it was right on the limit of the adjustment range. To be on the safe side, I ended up returning and swapping for a medium, which I must admit was a much better fit. If you are between sizes, definitely go for the larger size.
Delivery was pretty standard, taking 3–5 working days with useful tracking updates sent via email. The Slider was well packaged, and I like that the band comes in a pouch, which keeps it protected in your golf bag. It’s well-made, fastens securely, and has a premium feel. It might only be a carry case, but these small touches matter and show attention to product quality.

Material quality, durability, and chest fit
The quality of the materials used in the construction of the TRS Slider is excellent. The main band uses a seatbelt-style material that is perfectly stitched with no fraying. The plastic buckle is robust and keeps the strap locked in place, preventing it from slackening during use.
It’s clear that careful thought has gone into the construction of the band. Small rubber dots have been added to the back of the band, which may at first appear cosmetic but are actually there to help the band grip your shirt and prevent it from sliding down your chest during a swing. It’s a minor thing that makes a big difference.
The main band is quick and easy to put on around the chest and secure with the buckle. Whilst some users have reported that the arm loop is too small to fit around the bicep, I’ve had no such concerns. Granted, I’m not the most muscular of people, but unless you’re built like a prime Arnold Schwarzenegger, you should be fine. The arm loop is comfortable, neatly stitched, and the velcro is high-quality, keeping it securely in place around the arm.
Real swing improvements and launch monitor data
I’ve seen plenty of positive reviews online, but they mostly come from touring pros or coaches who already have quality swings. As an amateur golfer, I wanted to see how it performed for someone who actually needs the help—and I wanted to see real golf swing data, something often missing from the reviews I’ve read so far.
The TRS Slider is designed to keep your trail elbow closer to the torso. It definitely seemed a bit restrictive and unnatural at first, but that is the point. It allows for a slight disconnection between the trail elbow and torso during the backswing, but almost forces it into the correct position on the downswing. This is why it can work more effectively than just placing a towel under both armpits, which won’t allow the disconnect in the backswing.
For me, I find that the Slider helps me to get some width in my backswing whilst shortening its length, brings the club down more on plane (rather than over the top like I normally do), and also does a good job of getting me into a better position at impact. I’ve struggled with properly compressing the ball with my irons for as long as I can remember. Whilst this is still an issue, I do feel like the Slider helps me to get my hands slightly forward and the shaft leaning at impact, reducing dynamic loft and helping me compress the ball better.
To test whether these feels actually translated into real performance, I grabbed my 8-iron, a bag of Titleist Pro V1s, and my FlightScope Mevo Gen 2 launch monitor, and headed out to my garden practice net. After warming up and recording a baseline with my normal swing, I strapped on the TRS Slider to track the numbers.
Watch my full video test and launch monitor data review below.
One thing that stands out about the TRS Slider is how quickly it leads to swing improvements. The very first time I used it straight out of the pouch, my FlightScope Mevo Gen 2 data showed the following gains:
- Carry Distance: +6.6 yards (129.9 yds vs. 123.3 yds)
- Ball Speed: +4.1 mph (99.0 mph vs. 94.9 mph)
- Club Path: 70% more neutral (improved from -2.9° out-to-in down to -1.1°)
- Face-to-Path Control: Improved by 8.9° (down from a slicing 10.9° open to a controlled 2.0° open)
- Lateral Accuracy: Reduced dispersion, bringing shots 7.4 yards closer to the centre line
- Spin Rate: Increased from 5,469 rpm to 6,158 rpm, providing better stability and stopping power
What the Badger AI analysis revealed
To get an even more objective look, I ran the session data through FlightScope’s Badger AI tool, comparing my standard P770 8-iron swings against the swings wearing the TRS Slider.
The AI highlighted that my standard swing suffered from a wide range of inconsistent spin rates (dipping as low as 3,385 rpm) and massive lateral dispersion out to the right due to an open face-to-path relationship. By forcing a more connected trail arm, the TRS Slider instantly tightened my shot grouping, improved face control, and eliminated the severe push-slices. It proved that the device doesn’t just feel different—it structurally alters how you deliver the clubhead to the ball.
Best practise routines and swing drills
To get the most out of the band, I recommend practising in dedicated block sets—hitting 10–15 balls with the Slider on, then slipping your arm out of the loop to hit 5 shots without it. If you’re looking for step-by-step setup instructions, specific swing drills, and tips on how to integrate the device into your practice sessions, check out my complete guide on how to use the TRS Slider (setup and drills).
Key strengths and minor drawbacks
In all honesty, there’s a lot to like about the TRS Slider, and not much not to like about it, but here’s a quick run-through of the main pros and cons.
What I like
- Helps get you into the correct positions throughout the golf swing.
- Helps reduce over-the-top downswing movement and improve impact.
- Durable construction with no fraying or poor stitching.
- Easy to adjust and quick to put on/off mid-session.
- Can be used with every club in the golf bag.
- It’s a versatile swing training aid that can be used with or without a golf ball, in the practise net or even on the golf course.
What could be better
- If you go for a larger size, the excess band can flap about. A second fixing loop or buckle to keep this in position would be a handy addition.
Final verdict: is the TRS Slider worth it?
The TRS Slider has become very popular in golf, and it’s easy to see why. I can’t recall any golf swing training aid I have ever used or tested that has given me such noticeable, quick swing improvements, backed up by concrete launch monitor numbers.
It’s incredibly well-made, easy to use, and it doesn’t just claim to deliver, it really does. There’s no need to have in-depth knowledge of the golf swing or know what you need to improve with your swing. All you need to do is slip it on, hit some balls, get a feel for it throughout the swing, and try to reproduce it without it. In truth, it’s the number one thing I think every golfer could benefit from having in their golf bag.

Very impressed with your presentation. I like data and hate wasting time practicing without a purpose.
Thanks very much, Joseph. I think using the data as a way of backing up how useful the training aid is very important, and hopefully helps prospective buyers see that it did actually work for me!
Cheers,
Andy
