co2CREA Hard Case Replacement for Logitech MX Master 3 Master 3S Advanced Wireless Mouse (Graphite Black Case)Carbon Neutral Certified by SCS Global Services

This protective case for the Logitech Master S3 is really, really nice. It's a perfect custom fit for the one specific mouse, and fits like a glove. It feels completely durable enough to withstand any reasonable amount of impact that your mouse may experience within a backpack or travel bag, and the material is soft enough you wont have to worry about scuffing or scratching the mouse. It has a carabiner, which is almost entirely pointless, but aside from that there's nothing negative to say. The zipper functions well and opens easily. Overall very pleased with the quality of this mouse case.

Tal como las imágenes, muy bien por la empresa de reparticiones, llegó súper rápido, un día antes del tiempo estipulado y en perfectas condiciones. Es súper dura y perfecta para el Mx Master 3s, le quedó perfecto

Fits great (perfect fit actually). Keep the mouse protected during travel.Very well built

Fits perfectly, good quality materials!

At first glance, the case for the Logitech MX Master 3S (which is what I have), looks well made. Closely inspecting the exterior lining, it appears to be made of semi-rigid nylon. I believe this surface is water resistant, having had similarly clothed products before. But I do not know if it will let the water through. I'm not going to try it, but I believe the surface would help the water bead up and roll off.The presumably EVA shell seems rather sturdy and is moulded nicely to the shape of the odd-shaped mouse. There is a tiny loop next to the top stop of the zipper which allows the supplied carabiner to hook into. These are nice to have, but not essential for the purpose. Happy to have them anyway.Looking at the zipper, I notice the zipper tab is covered in a rubber-like material with the brand name engraved into it. It is large enough for me to get a comfortable grip and doesn't escape the pinch between the (I would say, fat) index finger and thumb while zipping up the case. The reverse zipper slider runs smoothly with a little bit of slowing down round the last corner before the case is completely zipped up. This zip configuration gives a beautiful look to the product as the teeth of the zipper do not show when closed.Opening up the case, two features immediately catch your attention. One is the raised bumps under the soft inner lining of the case which seems to be made of Lycra. The soft inner lining gave me the confidence that my mouse will not be scratched. (But that confidence did not live long because of a small design flaw. More about that later.) There could be some kind of foam under the bumps, but I am not certain of it. These bumps, I suppose, are intended to absorb shock. (But for the same reason given earlier, this may not be so helpful.) The other feature is the recess on the floor the mouse will rest on. This is meant for the Logi Bolt USB receiver. This immediately had me looking for the receiver which I had forgotten to take out of the box the mouse came in! (Luckily, I have a habit of keeping the boxes my gadgets come in.) Had I not seen this recess, I would probably have forgotten all about the receiver.Now come the problems. After placing the mouse and the receiver in the case and fully closing it, despite its lateral snug fit, the mouse was able to bounce up and down easily when the case was moved about. As it did so, the receiver also fell out of place as there was nothing to prevent it from being dislodged from the recess. The receiver has sharp edges and this could end up scratching the mouse. It hasn't happened, but the thought that it could takes away the confidence given by the soft spandex lining. Also, the excessive give means the benefit of the shock absorption feature is reduced, if not nullified. There is also an additional concern that due to the fact that the receiver could be anywhere in the case, if I were to open the case in a hurry, I could end up losing the receiver which could slip out unnoticed because of its size. Even if the receiver managed to stay in the recess, it could still easily fall out. Not good.Apart from the problems just mentioned, this is still a pretty good case and I think I can work around the problems. After putting the receiver into the recess, I could easily place a sufficiently thick layer of fabric lining cut out to shape to firstly keep the receiver in place and secondly reduce the give in the case so that I do not end up with a 'maraca' as one reviewer described it. (That was so funny.) As easy workarounds are possible, I would give it 4.5 stars. But that option is not available, so four stars it is.As a suggestion to the designer/manufacturer, I would say that it might have been useful if there was an elastic band over the recess to keep the receiver in its place. Also, if the give could be reduced by about 2mm, the mouse would not bounce around as much.

Excelente calidad y entrega oportuna

Totally worth it. Strong zipper, strong case and fits the shape of the mouse perfectly.
