Tiny but packs a punch!
I have a 4k DVR with front and rear cameras on my motorcycle. The DVR will overheat and stop recording after a while, so not to damage the unit. I bought this and put them on the DVR and no more overheating. The adhesive is strong, (I have a Harley that vibrates as a Harley should) and all the pieces I add to the DVR are still intact. Good product, I strongly recommend!

Tamed the Notoriously Hot T7
Slapped two of these things on a 2TB Samsung T7 that I'm using this external storage on a PS5. The T7 is notorious for running really hot, much hotter than its predecessors. I picked these up thinking they would help avoid throttling. And they do. They spread heat easily and definitely helped to improve sustained performance. I see it in download and transfer speeds 3/4 of the way through. The T7 used to throttle like crazy near the end of a long download. It just doesn't now. Worth considering. Just be careful where you stick these things. Getting them off is a pain (use dental floss).

Pretty good
These are good quality heatsinks. Be aware that the supplied mounting tape works but doesn't conduct heat very well. You can greatly improve the heat sink effectiveness by skipping the tape and using thermal paste instead.

Works
Used on a fanless mini PC. Works well to keep the mini-PC cool. The adhesive appears to work well.

Cooled my SSD on ROG Ally but need some modification
Saw a few ROG Ally videos and came across this mod for the SSD. This heatsink does work and it did improve the FPS; however, if you are using this heatsink for the SSD, you will need to file down a corner near the GPU heat pipe to avoid damages to it during reassembly.

Fast delivery
As advertised. Would buy again.

The adhesive on these is so strong -
I got them because my ASUS motherboard Southbridge gets SO HOT. These stick nicely to a clean surface (another flat heatsink) and I've even got a tiny 30MM fan screwed to it. Brings the temp down ~15 degrees.

Did what it said it would do and what I needed it to do.
I have a older Crate solid-state guitar amp. As long as I've had it, I've thought the output transformer got awfully hot. I tried mounting a small "whisper-fan" in the cabinet, but the whisper was louder than I liked, and it used up another outlet on my power bar. A friend suggested something like these small heat sinks. Got the six-pack, stuck 'em on three sides of the transformer, and it made a very noticeable difference in the temperature. Best thing about them was that they came with heat-transmitting tape already on them. No more fan, I'm very satisfied, and the whisper-fan has been retired. Hoping to get 20 more years out of the Crate amp.

Effective on 3D printer motors, but thermal pads a little too thin.
Lowered the temps off my 3D printer motors by about 10°C during particularly overnight prints. Only 4 stars because the thermal pads are very thin, so any uneven surface (such as the side of a printer motor) will lead to relatively poor contact, it still works, but it could be working a lot better with just an extra 0.5 mm.

Ideal for cooling gaming systems
Swiftly delivered and fitting a handheld.

Works great for ROG Ally with a slight mod
After installing this in my ROG Ally, I saw a stable 8-10 degree C drop on Diablo IV. I highly recommend doing two things: 1. Order qty 1 of 1mm Gelid GP-Extreme thermal pad. You will cut this to size after removing the thin factory installed pad. 2. Take metal snips and trim the sharp corner off from the base of corner that goes against the fan heat sink. (See pic for metal exposed corner) You risk denting the heat sink from the fan if you don’t do this and the back will bulge slightly because it’s putting pressure on it. Trimming the corner fixed that issue and prevents damage. Now for the install. You will need to remove the black sheet covering the internal components. You can cut it to fit back in if you like. The new heat sink needs to be fit into the back plate side to close the unit properly. Do not try to close it with it sitting on the nvme. There’s a hole that one of the heatsink legs will slip into. You don’t need to cut any plastic - it fits perfect.
