ZOpid Mini Cordless Handheld Vacuum Cleaner - Portable Desktop Vacuum for Keyboard, Laptop, Car, Office & Home Use | USB Rechargeable with Brush & Suction Attachments | Perfect for Cleaning Electronics, Crumbs & Small Debris

Ok, first off, the attachment device (plastic thingie) does not stay on the vacuum well at all. And to be honest I've found that the flat tool (not the brush) works much better at picking up debris than the brush. It's not a very powerful vacuum at all but if you hold it just right it works ok. It is very cheaply made and the price is fine for this product so I can't really complain too much.The battery door is not too hard or easy to open. It's good. It seems sturdy and "quality" if you can call anything on this thing "quality."It is not too loud at all. I can't attest to the battery performance of it since I've had it less than a week and used it maybe 6 times to clean up my little table and my laptop keyboard. It works fine for what it is and it's cost. I did read a review of this that someone said they use it to clean up kitchen drawers from crumbs, dust, etc. Yes I can see that would work since it's not USB powerd. I like that it's not tethered to the computer for power. So that's a plus.The attachments (heads) fit okay, they have a tendency to want to loosen a bit (almost fall off) if it's bumped harshly. But they are snug enough. I would have liked (in the perfect world) for the heads to snap into the body of the vacuum.Honestly the attachment holder is useless. It falls off so easily. I don't even keep the attachment holder and other head attached to it anymore. It falls off too much.I think the crevice tool is a better head for it for basic cleaning on the desk, etc than the brush. The brush attachment has 3 tubes within the long bristles that suck up the crumbs and I didn't find it very effective at all. I don't even use that one anymore. I only use the crevice tool for everything. I mean, what are the bristles supposed to do anyway? It's marketed to be a computer/desk/keyboard vacuum and i can see that if you were cleaning the cpu fan or the case fan of a tower you could use the bristles to knock off the dust from the fan casing but other than that it seems useless.So with the less than stellar suction power, the falling off of the attachment holder and the crappy brush attachment head I give this 3 stars. It works as intended. Nothing great or horrible about it.This Zopid vacuum is basically good as a preventive measure against dust accumulation on the mother board of computers or electronic board of receivers or music amplifiers. So, when the these get somewhat dusty on the outside, one needs to take the cover out, and then vacuum the electronic board. But, once it's too dirty after a long time, the dust get accumulated in like cottonflakes here and there on the electronic board, then the only good way to get rid of them is to use a hand held vacuum like Shark or Fantom of around 4 or 5 Amp. Then after vacuum them, to complete the task, one needs to use the hair blower which has an extra function of blowing out just the air (not the heating air like most of others) to blow the small dust particles remaining. Even the hundreds dollars desktop vacuum cannot do the job as good as these Shark, Fantom. Why so? Just compare the Amp number, the answer is there. But, better not use the big house vacuum which such high amp (8 Amp or more) to vacuum the electronic board, as this possibly can pull out tiny components such as tiny transistors. With hand held vacuum, to guaranty that small electronic components cannot get loose from their soldering spots, one needs to direct the flat nozzle (more or less) perpendicular to, or besides those components when vacuum them. Anyway, a vacuum of 4 or 6 Amp cannot break loose the components from their soldering spot, whatever orientation one directs the flat vacuum nozzle. Me, I already use a hand held Shark of 5.8 Amp to vacuum the electronic board of my vintage Sansui with no problem whatsoever . And if the outside cover stinks due to its old age, one just needs to pass a new layer of paint over the old one !In brief, to avoid spending your energy through having to use such hard means on your computer, you just need to pass this Zopid on the outside cover of your computer times by times after turning it off. Just use the flat nozzle, throw to garbage the brush nozzle as this is like a toy with no power whatsoever in function (Just put your finger and check, you will feel nothing).Does not work at all. Brought as a gift for Christmas and I just got it out to try for my other half this very moment to find it doesn't even move a dog hair on a table let alone hoover between keyboard keys. Total waste of moneyA lovely little vac, just what I was looking for. I wanted to use it to vac crumbs up on our kitchen sides before I wiped them with a damp cloth. Not very powerful but does the job adequately.Purchased to use on N gauge model railway. Does the job of dust and scatter collection perfectly without disturbing scenery.Bought this for my mum who is not very mobile to clear up her tobacco spillage. what a fantastic gadget works like a dream she is delighted. Good delivery time too. Definitely recommend!Extremely useful for all awkward corners on trolleys, coffee tables, anywhere where crumbs and dust gather. The computer doesn't, get a look in!
