The Precision 3 in 1 Screwdriver Keyring is certainly a bargain at $7.
It can come in handy for small things like putting a desk fan together etc. With those little screws that you get. The colours of the tool are nice (I bought 2 and received a red, and a blue one) – even though you don't necessarily get a say in which colour you get, they're pretty gender-neutral colours anyway, so it isn't that big of a deal.
The only slight criticisms I would have of it is that only 2 out of the 3 bits can easily fit inside the ‘bit storage’ area – and since the backside of where the bit that you want to use is placed is magnetized, these bits that are placed in the storage slot literally just behind it, get magnetized towards it, and stick there, so if you need to get your other 2 bits out of the bit storage, you literally have to whack it on your hand if you want them to come out (you may have to stick something inside the bit storage to prevent the magnetization on the inside to prevent this perhaps-). It's something the manufacturers probably didn't think about, and is a slight inconvenience when you want to change bits out.
Since there's not much difference in size between the 2 x Phillips: #0 and #1 sized bits, I would probably recommend that if you get this item, perhaps you only need the #1 bit which is only ever so slightly bigger than the #0 bit, and keep the Flathead bit in the bit storage. Perhaps only use these 2 bits out of the 3 that are included (Phillips #1 bit and Flathead 2mm bit), so that way both bits can be put into storage when you are carrying around your keyring – as you don't want the current bit that is placed on the tool to fall out – because remember, it is magnetized, so while it may not fall out because of this, it is still very possible that the current bit placed on the tool can fall out if you don't store all the bits when carrying your keyring around/when it's not in use.
Overall it's a good product at a fair price, with only a few slight criticisms I have of it that the manufacturers could have improved on.
