Very useful gadget you don't know you need
Neat little gadget that I didn't realise I needed! Definitely makes some magnet improvement over standard magnetised bits. Its small size does not get in the way at all and the durability has so far been good with very little wear after a fair bit of use. Very good value for money, I'll be buying more for my other Makita drivers

Good little quality of life upgrade
Good little quality of life upgrade. Holds screws so you don't need to worry constantly about dropping them when working in tight spaces. It's cheap and will make life easier for you.

Good but not outstanding.
Does the job but does sometimes fall off which is annoying.

Handy magnetiser for screws
Handy bit of kit to keep screws stuck to the screwdriver bit by using internal magnets. Only works on long 1/4 inch bits

Seems to work ok, but gets in the way sometimes
Does what it says it does, the magnet is strong enough for bigger screws, I tried up to 5mm x 100mm screws and it seems to hold well. The only downside is that it covers most of a 50mm impact bit, so if you need to see where the tip of the bit is, then you'll either need to try longer bits, or a different solution. Update: Used this a few times now, but found that on a 50mm bit, it covers most of it, so if you are screwing into a recess, the Mag Boost gets in the way. Longer bits would probably work better, but they are more expensive, and not worth the faff. I have gone back to a Wera Impaktor bit holder and standard size impaktor bits.

Compact durable works really well, a handy thing to have in your drill case.

Tiny little thing that really works well
I saw this recommended in a newsletter I receive and thought I would give it a try, as it was only a fiver. It arrived and was much smaller than I had expected but it works well. It slides over normal size screwdrivers, almost pulling itself on (see my video), and when in place your screwdriver channels the magnetism to hold most screws in place on the end of it. Really nifty piece of kit, which really comes into its own when you have an awkward spot to drive in a screw, or remove a screw and not drop it once it's out). Really tiny, too, so easy to pop in your toolbox or pocket (and equally easy to misplace, of course!).

A powerful little magnet that makes a number of jobs much easier at almost no expense
An amazing little device. Slips over the drill bit and allows you to hold a screw in place while working. I used it recently to change hinges on the doors throughout my house and it made the task so much easier. It’s also very reasonably priced so it makes it one heck of a bite. I certainly recommend it.

No siempre lo barato sale malo.
Muy bien, un agarre perfecto de los tornillos y buen ajuste a un destornillador manual, o a un bit para atornillador siempre y cuando sea de tamaño largo. El tornillo si es de acero, o sea la mayoría, queda firmemente fijado, y aunque lo.menees no te caerá. De precio muy bien, solo 2,5€

Works great but be carefull of the type of bit you are using
This adds a lot of magnet power but you need to have the right type of bits otherwise it is a really bad fit. I tend to use the impact ones that are quite thinner in the middle part and it is not a good fit with this. You need to use the ones that have the hex part all the way and it will do wonders.

Excelente produto. Cumpre o que promete. E bem menor do que imaginei. Graças a Deus. Mas, o imã é bem forte. Podem comprar sem medo de se arrepender.
