Vilros 40 Pin GPIO Solderless Hammer-in Header for Raspberry Pi Zero, Zero W, Zero 2 W, Pi Pico 2 W – Compatible with Pi Zero Case, Easy Install (Header Only, No Soldering) [Pack of 1]

It looks good and all, but I'm forced to buy another one for £25 to get the support rig to hammer it in, due to multiple failures and not wanting to risk my hardware further.

Solid spring loaded pins. Fits my pi zero 2 w perfectly.

You don't need a special tool to install these. I just got a small piece of soft wood and cut a notch out where the pin header goes, then tapped it in with a small hammer. So much faster, easier, and more reliable than soldering!!

I broke 2 of these trying to install them into a Pi Zero W2 without the special press you have to buy. Better to buy your Raspberry Pi Zero, Zero W or Zero W2 with them already installed. The pins widen out below the black plastic & do NOT fit into the holes without the special insertion press. Neither by hand or with a board & rubber mallet are you going to get this into the Zero's circuit board without the great likelihood of breaking it. IF you put together a lot of Pi Zeros, it pays to get the press. But the cost of the Pi Zero with GPIO pins installed is well below a naked board, this GPIO header & the special press. You can also look for a GPIO pin array that is easy insert, but requires 40 delicate solder connections to be made under the black plastic, but it's not a task for somebody who doesn't solder often & well. At least these are sold by Vilros, an approved reseller of Raspberry Pi products in the US. You see too many Pi products from strange Asian "manufacturers" with prices up to 100% or more above legit retail.

after using the tool to hammer this on my raspberry pi, the pins were loose and would not secure properly

I've had better luck with the pins not bending with the Vilros brand as compared to Pimoroni solderless headers.
