(Update 7Jan22) I only use the non magnetic model, (889/4/1). I lost it for a short while, and immediately bought a second one. After a year I found it. Now the non magnetic one is on both my impact drivers. (Original review) The SD label on the item listing refers to the packaging. It is the same as this item. (added 2APR2020) This is a good tool. Swapping bits is pleasantly easy compared to the other options out there. You have to fight with the ones from other brands, and then use this item to understand that opinion. The ease of use is so nice, I'm benching all my 2 inch bits and I'm going to use this with bit inserts going forward. I will continue to try to find something that does a little more. This Wera bit holder is extremely easy to use with Milwaukee bits. They pop in and out with ease. This holder is much better at inserting and releasing the bits compared to the Makita version. The Makita is just plain irritating to use, because it doesn't release the bits. The Wera retaining system is very good, and easy to manipulate. The bits do not fall out when the screw is done, like they do in my other magnetic bit holders, (Ryobi, Milwaukee, Makita, Stanley...). I have both Milwaukee and Wiha 2 inch bits, and they are both fantastic. I would like to have a simple solution to make them better at holding the fastener in both downward and horizontal pointing angles. I also have a large collection of Milwaukee bit inserts, and a small collection of the Makita inserts. I have the Makita B-35097 Impact Gold Ultra-Magnetic Torsion Insert Bit Holder. It does hold the screws at weird angles, with the insert bits. However, it is clunky to use. The bits fall out in use and the bits are frustrating to change in and out. I want this part to also hold the screw in position. That would be perfection. I thought the metal ring around the bit might be a rare earth magnet, and slide down to hold a screw in both downward and horizontal pointing angles, but it does not. Dewalt makes a part that comes in a 3 pack, that slides up and down the normal 2 inch bits from most brands, and magnetically holds a screw in place. I will try them out, but I would prefer to use something like this item, that makes bit changes ridiculously easy. The built in impact driver bit holders on both of my tools (Ridgid and Makita) are okay, but this tool is so much smoother, that I will just leave it installed. The search continues. (Updated) It appears Wera offers another version, in line with what I want. It is the 887/4 RR. It has the magnet built into it. I just ordered that one. You will also find the 887/4 RR SB. They are the same product. The "SB" refers to the packaging. I will post a review for that as well, once I have my hands on it. I'm keeping both, if the 887/4 works just as smooth. I have two impact drivers, and it gives me options for both. (Update 24Mar20) I like them both. I recommend both. If you are pulling and installing screws, use this tool. If you are just installing a bunch, use the 887/4/1. I included a picture of all the ones I have for reference. The 889/4/1 is the smaller one of the two with green accents. See my review of the 887/4/1 if you want to learn more there. It has the same picture. (Update 2Apr2020) I've been working on a project lately. I found this, and its friend, the 887/4/1, are very good at holding all brands of bits, even ones that sometimes slide out of magnetic holders. And they hold them tightly. I really appreciated this, as I have one set of nut driver bits that keeps falling out of the other four bit holders I own. Problem solved!
