They work well with my old iPod Video (generation 5. They do work fine on my Pixel 4 XL still. Note: It took longer than the Prime 2 day so if you need it in a rush, this might not be for you but if you can wait, then i would recommend this part for you. If the contents are poor at best and the case cant be used for a decent "make your own" kit because its poor quality plastic and NOT WATERPROOF, then what is the point? Super disappointed with this on every level. The sealant product is also watery and thinner than before ,Poor quality all around. He says they are easy to zip up and very practical. If youre buying this I would suggest reading something of any of the three characters so you have a grasp on who they are. These beads are very pretty! but in more advanced and full 4K situations dont try them. I used the foot pads on a pair of heels I had worn previously which left me with significant foot pain.
