Bosch has always been the hallmark of high quality, and this drill bit set is no different.(All us VW fans from way back remember Bosch parts as the "go to" parts replacements. When I recently saw that they had introduced some battery operated drivers and drill bit set combos, my first thought was that it was probably high quality, solid, and soundly manufactured, and that I would not be disappointed with the purchase. Just like then, so now - pay a premium price but avoid a lot of trouble down the line!And indeed these bits are high quality. Easy to remove, decent enough value for the money - (you're paying for the brand, and in this case, the brand holds up to its reputation very well!) (At least in my experience so far!) and sure to last a long time. These are the bits that you keep and re-sharpen when they get dull.I've thoroughly enjoyed using these bits, well, as much as one can enjoy using drill bits - they really bite - the wood that is - and work as they're supposed to. Kind of took me by surprise in a way, having been used to bearing a lot of pressure on the drill, but these went in like a hot knife though butter. Good drill bits can make a big difference.I also noticed that the metals seem to be stronger than some other bit sets I've purchased for less elsewhere. You can tell just by looking at the metal and seeing the machining and feeling the edge. (Make sure to have a bandage handy if you do feel the edges - - - they're sharp!)I would heartily recommend this bit set as an addition to the Bosch battery operated drill and impact driver set, or even as a "stand-alone" for someone who already has a favorite drill.In my opinion, these bits live up to their name and implied quality of the brand.And that's not all - the bits come packed in a very usable plastic case with bit holders that are actually easy to remove the bits from and put back into. Yeah, this helps keep things organized. No cheap case either, seems to be strong and durable and should last as a bit holder for many years to come.Nice deal all in all - totally recommend - good quality for the money and a brand name to boot! No doubt they will last for years!

The sets are all great and every bit is useful the only issue I’ve found was the sets that have sockets the sockets don’t lock on to the socket adapter or if you try to use them with a ratchet.

this set truly has everything I need for various applications in wood, metal, and masonry. The included case keeps everything neatly organized, which is a huge plus for me. It's incredibly handy to have everything in one place, saving me time and effort when tackling projects. Plus, the value for money is exceptional – this set provides excellent quality at an affordable price point 30$ for 91 pieces.While the drill quality could be improved for longevity, I still find this set to be a fantastic investment. Overall, I highly recommend the BOSCH MS4091 set to anyone in need of a comprehensive drilling and driving solution. It's reliable, convenient, and offers great value for money!

The case is brilliant, and that's what you're paying for here. It's right in the middle between soft and brittle and it feels like you could throw it off a building and it would be fine.The bits all fit in very snugly and can take some effort to remove. That's the point. When you look at how tough this case is, it's obviously designed to survive being dropped, and guess what happens with easy to remove bits when their case gets dropped? They pop loose. That doesn't happen here, and that's clearly the intent. Shake this thing as hard as you can and nothing comes loose. You can barely hear anything RATTLING everything fits so snugly, which again, is the point of this kit.The quality of the bits is not high. But this is a TEN DOLLAR KIT with an amazing case, how much quality did you expect to get from FIFTEEN bits? Bosch sells EMPTY bit cases for $6. Now subtract the sockets, adapter, screwdriver bits and holder, and what are you left with? The combined value of all those drill bits can't be more than $2. It's pretty plain to me that you're supposed to replace them as you go with higher quality bits. Had they all been regular quality Bosch bits, this would have been a $40 kit instead of a $10 kit. Instead you can replace what you need and build the kit the way you want. I call that flexibility.When criticizing this set, do it in the context of it costing $9.99.
