Fixed my laptop!
I tried everything to get those stubborn ssd and heat sink screws off my laptop. I tried heat, rubber bands, all the right screwdrivers and the big pliers at home but none worked and everyone told me to get those overpriced vampliers But this mini plier did the job just right It was my last hope and it worked wonderfully

It really works
This was the last resort for me as I had needed to disassemble an old PS3 but one of the screws on the power supply was badly stripped. After trying the rubber band method and tape method with no luck, and not being able to use a dremel due to the awkward position of the screw within the chassis, I bought this and was able to remove the screw after a few minutes. The hardest part was getting a solid grip, due to the small size and awkward position of the screw but after a few minutes of effort, I was able to remove it and complete the work I needed to do.

Mi hanno salvato
Stavo provando a svitare le viti che bloccano il sistema di raffreddamento del mio notebook per cambiare la pasta termica (visto che da quando l'ho conprato non l'ho mai fatto) e nonostante il cacciavite con la punta più adatta che avessi, un paio di viti si sono spanate. Dopo aver provato il metodo dell'elastico, della colla, anche dell'estrattore (sono spesso delle fregature queste punte) sono incappato in queste pinze e ... finalmente sono riuscito a toierle con facilità e anche con mio stupore data la facilità con cui le ho svitate. Sono davvero ottime, ben rifinite e di un metallo resistente, mi hanno salvato. Giusto un consiglio, fate comunque attenzione quando stringete la testa della vite perché il metallo delle pinze è ovviamente più duro di quello della vite e potete intaccare il bordo rischiando poi di diminuire la superficie su cui fare presa, nonostante mi sia successo comunque sono riuscite a fare grip anche sulla piccola superficie disponibile della vite. Vi allego la foto di una delle basterdelle (vite con testa piatta! La più infame probabilmente da affrontare).

Si barriste el tornillo de una SSD, esto sera tu salvación!
Tuve una experiencia de terror al ser principiante en estar modificado mi Steam Deck, para amplificar su SSD. Al principio tenía demasiada confianza de que iba a ser un proceso facil, ya que habia tenido poca experiencia haciendo cambios similares. Confiando de mis herramientas (no tan buenas al parecer) barri este tornillo, y hice lo que nunca debes de hacer que es forzarlo hasta que pierda forma. Intente de los dos métodos universales: el del pegamento y la liga de goma. Ninguno funciono. Buscando en foros de Reddit respecto a este tipo de problema, especifico del tornillo del SSD de la Steam Deck, encontre a alguien que sugerio esta herramienta, fue el llamado divino que me hizo tener la solución! Al principio no tenia esperanzas, ya que intente ligeramente hacerlo con otra herramienta similar a esta, pero no funcionó. Pero, la compre aun asi, y vaya que ni fuerza le tuve que poner para sacar el tornillo! Una maravilla de herramienta. Tuve mucho cuidado de no dañar nada de la SSD de fabrica, y no hubo nada de problema. Muy recomendable, al parecer ese tipo de tornillos son un dolor de cabeza, al ser tan delicados. Así que si también sufres de este problema y te llevo a esta herramienta, mi recomendación es: ¡Comprala! Funciona bastante bien

Amazing pliers for screw extraction! Thank you to whomever designed these. Just brilliant!
While changing the hot end on my 3d printer, I ended up stripping one of the screws. After going through all the online forums someone suggested these special Japanese screw extractor pliers. I did a quick search and found these on Amazon. As I was desperate, I ended up ordering one of the recommended pliers. Unfortunately I had forgotten that the screw was only half exposed and there was not enough room to get the pliers onto it. We ended up drilling into the screw which broke the rounded head off. So now we only have the stub of the screw exposed (oh oh). Miraculously, these pliers were able to grab onto the stub, and as a last Hail Mary, we were able to twist the screw out of the hole. So these Engineer pliers basically saved the day! The tip of these pliers were designed to grab onto tiny screw heads used in electronics. The pliers themselves don't feel cheap (or look cheap) in your hands either (thank you Japanese quality). 100% worth what I paid for them, and zero regrets buying them. They will be helpful, heaven forbid, if I have to deal with a situation like this again.

Excellent for small stripped screws
I was skeptical that this product would work on a badly stripped M3 screw but I figured for the price it was worth a shot. It far surpassed my expectations and the screw was out in under a minute with minimal damage to the surrounding area.
