Better Than the Milwaukee Option
Perfect fit and great retention. It offers better versatility than the OEM version from Milwaukee. I recommend this to anyone who wants increased utility at a reasonable price.

Works great
I like it. It dose make the drill a bit wider but the magnets are good so it doesn't drop the bits at all and its handy to just be able to grab the drill and go

Great product
Absolutely love this bit holder. The magnets are very strong and I have never had any issues with the bits falling out. After a year of daily use the screw that holds it on the impact has come loose afew times but it’s not a big problem. Overall this is a great purchase, especially for electricians.

Great addition to my impact.
This fits and looks like it belongs on my impact. It's perfect to hold the attachments I use most frequently without having to go back to the box every time. The screw holder magnet is a little bit too weak to be a reliable holding spot for my screws though, unfortunately, unless they are tiny and youre not vibrating it too much, which I tend to. Also, the glue holding in the magnets is not that great.. I had one magnet (so far) pop out when impacting, and it is not that easy to get back in its hole because the magnets around it pull it sideways. I have seen that on other reviews as well, maybe the manufacturer could take that into account and improve it. I would take it down a star for that, but it wasnt THAT big of a hassle, and I still really like it and overall feel it's 5 stars. Besides that, they are strong magnets and can hold a 3/8 drive adaptor with a socket on it. Handy piece of equipment. Be sure you don't let rust fall in there though because it's hard to get out and makes the magnets not stick as well.

Game Changer - Recommend for Mechanics
It's such a simple upgrade that really increases work efficiency. Simple, quick, psinless install. Veey good tool fit, and not too clunky. As a mechanic, I primarily use 8,10,12mm nut drivers, & it is tedious keeping track of them in the middle of all the other sockets, nuts, & bolts. Having them right there has made a world of difference wirh splash shields, bumpers, under hood, & interior work as those task often use 2 or all 3 of those sizes. The downsides & why it got 4 not 5. The side magnet is basically useless for holding nuts & bolts. Impact rattle them off. Same with the bits as well, only sometimes unfortunately. I've had to fish some of my bits out of an engine bay a few times. I think if the magnets were stronger, it would be perfect.

If you’re using M12 tools, this is a must-have accessory.
This magnetic bit holder has quickly become one of my go-to accessories for my Milwaukee M12 tools. The magnet is strong enough to hold bits securely during heavy-duty tasks, but not so strong that swapping bits is a hassle. It feels durable and well-made, with a solid metal construction that stands up to frequent use. Using it has made my work much faster — no more dropped or lost screws, and the holder keeps everything right where I need it. It’s compact, easy to handle, and fits perfectly with the M12 drivers.

Upgrade your drill!
I definitely consider this an upgrade to my impact as well as my hammer drill. I’ve got a combo of this unit on one side then the magnetic bit holder (also from Simon tools) on the other side. Super useful combination, six bits should cover most things I encounter on the one side, then screws and drill bits on the other side (see pic). The plastic construction on the unit is pretty tough with a rubberized magnetic section (magnet is little weak). The rubber magnetic patch will hold a number of loose screws as well. The magnets in the slots are very strong, no worries about tips coming out. I really love not having to grab a box of tips when I need my drill for something. I keep a couple of adapters, Phillips, and a torx bit in there.. maybe a slotted. It’s become one of those tools you can’t imagine not having. Just an extension of the drill. I read where someone wrote that the drill becomes top heavy. I haven’t had that issue myself and I thought I would. The drills having remained fairly balanced. Full disclosure I am using the larger bottom batteries, 3.0 and higher I believe.. that helps balance the drill. I’m a new fan of Simon Tools!

The bit holder with the finest fit and finish among them
I have tried a few bit holders, but none have been as secure or durable as this one. The magnets are no joke and the way the holder is produced makes it "lock" onto the impact driver, meaning I've never once needed to tighten the screw unlike with this product's competitors. I recently had a magnet come loose, and Simon deemed it a manufacturing fault and promptly offered to resolve the issue. This is a quality product produced by quality people.

A must have for the M12
Made my job 10x easier having all my required bits for regular work all in one place, decent magnet and can even hold a few screws for ease would recommend for any m12 user
