Thick as a brick? Yes. Still awesome? Yes!
I'd like to give a description for those who felt as I did before trying these. Prior to giving these a shot (out of curiousity) the thickest picks in my stable were 1.1mm D'addario black ice, and my favorite picks were the smaller 0.8mm from the same brand. My thinking was: how could a 4.2mm pick be good in any way? Well, it's all about the edge bevel they put on it. That bevel has the precision of a smaller pick, but it also provides a sort of energy to your picking hand such that it assists in "bouncing" to the next note. It's hard to describe - but it has a very different feel from what I anticipated. Pros: - material is very hard and feels durable. I have a LOT of picks that are worn down to an oblong circle shape, this is a lot harder - how they change your playing as described poorly above. This is the biggest delight and I encourage anyone to give them a shot based on this - texture provides adequate grip, no complaints - (listed as both a con and a pro depending on your perspective): sound with these is a bit brighter, with more clarity Cons / gripes: - they could have made this a triangle pick in a similar size pretty easily. - (listed as both a con and a pro depending on your perspective): sound with these is a bit brighter, with more clarity - It's a pretty expensive piece of plastic really

Why haven't I used this 10 years ago
Literally the best pic for virtuoso playing I played the same pic like many others the Dunlop purple 3 mm but they always kept sliding off as I was playing faster because of the sweat in my fingers but this one is slightly thicker which feels ergonomically better but best of all what shines is the embedded grip design that you have to feel to understand you can literally hold this pic so light in your fingers with the added thickness and that grip from the pic design it will not fall out because we all know you cannot grip the pic hard during Yngwie Malmsteen runs or Michelangelo licks keeping the pick in your hand light and secure and the beveled point on the pic slides so nicely it was amazing playing for the first time I want to buy a thousand of these to keep LOL

Overall, the best and most versatile mass market pick I've played
I've been playing on 2mm graphite picks for years. I love a thick pick with a quiet attack, but the standard pick shape creates inefficiencies in my playing. This pick, due to its extreme thickness, shape, and contouring, is the best playing and most versatile pick for the way I play (constantly changing techniques). The beveling is equal on both sides; steep and gradual, creating a dull but articulate "axe" edge perfectly centered at 2.1mm in from the gripping surfaces. This edge is thin enough to get a "thin pick" attack without much effort, but the convex bevel makes it easy to get any other attack you desire. The only kind of attack you can't get out of this pick is the scratchy clack of a thin pick playing rhythm-- when you attack like that with this pick you just get the sound of the strings, not the sound of a pick, which I think makes this pick better. I hate hearing the pick, I just want to hear the strings. My only complaint is that the pick material, Ultex, is too resonant during the attack. I hate pick "chirp" and this pick does produce more chirp than I'd like, but there are ways of changing my attack to minimize it. I would love to have a pick like this in Delrin or Acetal. Until Dunlop offers this pick in a different material, I'll probably just be copying it's shape using the thickest buttons I can find in my mom's button collection.

If you’re not buying custom, BUY THIS PICK.
I’ve been playing guitar for 19 years. This has got to be the most comfortable pick I’ve ever used. I always relied on the smaller yellow tortex picks for most of those years, but recently I decided to try a thicker pick and all I can say is WOW. I don’t even need to try, my thumb and first finger just naturally rest on the grip and keep it stable with almost zero effort. If you like a chunkier and rounded sound, definitely would suggest these. Works especially well for speed, and pinches have never been so easy. I never review anything but this pick deserves high praise.

Very nice material. Great feel in my hand. Nice sharp point that holds it's shape after use and is slick on the strings so you can play fast easily. Best pick I own now.

4.2mm Flow Pick
Playing bass i like really thick picks and sound matters a lot. these are as close to the sound your fingers make as i can find. They have 0 flex to them so if that is what you're after i would look elsewhere. But for anyone that wants a really thick pick these have been my favorites.

Plectrum.
It picks the strings very nicely. It grips really well too, no turning and slipping.

Ergonomisk och bra kvalitet
Jag som har nervskador och är svag i höger hand då jag ska greppa plektrum tycker detta plektrum är kanon. Är mer avslappnad i hand och handled då det är mer ergonomiskt och enkelt att greppa bra pga. Dess tjocklek.

My only pick now
Having played over 40 years, I've pretty much tried everything, including handmade custom picks. These are now my go to pick for acoustic and electric guitar. Here's why: 1. Rigidity: Many years ago I learned that rigid picks are the only way to go if you want to be able to pick fast and accurately. It's all about feedback: any flex reduces your connection. So for many years my minimum was 2mm, so clearly at 4.2mm, these fit the bill. 2. Fat picks reduce strain. A revelation to me was when I tried a custom 8.4mm pick: it was simply easier to hold. This is basic ergonomics, but was very counterintuitive. While I still have and use that monster, through experimentation I found that 4mm was the sweet spot between ease of grip and thinness to navigate string separation. 3. Microdot grip: the bane of many a guitarist is a pick slipping out of position between your finger and thumb. While custom picks address this with drill holes, the microdots on this pick seem dimensioned to interlock with the grooves of your fingerprint, resulting in a "lock" that is close to magnetic and the best I've ever encountered. 4. Ultex: so far, in my experience, this is the best composite produced for guitar yet. Hard-wearing, light, with a feel and tone comparable to real tortoiseshell, this material is simply the best I've tried. 5. Shape: the graduated point of this pick, inherited from the venerable Dunlop Jazz pick, gives the perfectly predictable and clean string release required for accurate and clear note articulation. In this case, the sculpting is perfect not only along the flat plane of the pick, but also across the cross-section, giving effortless sweeps and alternate picking. 6. Size: this is probably the most personal aspect. I prefer this size, but for those of you accustomed to the smaller Jazz pick size, this may be too big. 7. Price: having paid upto £30 for custom handmade picks, these are actually really good value for money and actually outperform those more expensive picks, largely due to the Ultex material and the microdots. 8. Aesthetics: who doesn't like a translucent forest green pick with "420" incribed in the middle? 😉 Overall, these picks work perfectly across nickel, steel and even nylon strings, giving a clear and beautiful tone. I've now built up a stock of 50+ of these and use them exclusively for all instruments other than bass or some some of my more narrow-coursed instruments (e.g. laud, where I use 2mm Ultex). They are that good.
