Ecola Vacuum Cleaner for Keyboard Notebook and Car

I had no great expectations, but the brush is the most effective piece of this product. I consider this a total waste of my money. There is absolutely no suction to remove dust nor any movement of air from the exhaust while running. I tried changing the batteries around backwards thinking I may have put it in wrong, but it provided no movement of air with batteries in either direction. By placing a finger over the intake or exhaust will cause a change in pitch of the motor, but you do not see any change in the movement of air. It appears that the motor needs air to operate, but does not move any air. I doubt if there is a fan inside the product. The exhaust bag does not even move or change in size when turned on with batteries.  Ecola Vacuum Cleaner for Keyboard Notebook and Car EDIT: And almost 2 months after purchase and this review, I receive the following message from the seller "Friends Equipments":If the item did not meet your requirement or not satisfied with it,Would you please return it back ?With best regards,Friends EquipmentsMichelle ChenTo answer your question: The window to return the item ended a month ago and the cost to return would exceed the value of the item. Item cost was $16.88 and cost to return was about $15. Not worth my time for less than $2. And by now, I have thrown away the packaging. This should have been sent the same week as my review and an offer to pay for return since the item should never be sold in the US for this purpose since it does not work.

This is our 'generic rating' for any good product we have purchased from amazon that works as expected. With all the products we buy on amazon, we usually don't have time to write individual ratings for the good stuff. If you see this review coupled with a 5 rating you know that 1. It's a verified purchase. 2. We have actually used the product and 3. It worked fine for us, so we recommend it to others because 4. It's worth the money.If I get a bad product, or one that doesn't quite live up to expectations, I will always write about it specifically.

You would be amazed at what you can use this for. I also used it to clean gas fireplace and gas hot water tank in my rv

After finally pushing the AA batteries into the chamber, I find that the cover does not close completely. Also, it does not pull very much air, and is noisy, as well as being very stinky, like an electrical fire.I was looking forward to using this, but it is not even workable.

A good little vacuum of you aren’t expecting the performance of a room vacuum. It is good for removing light weight materials from small areas. I use it for removing ballast from switches on my model railroad.

Item calls for 3-V batteries, which in the USA are photo batteries. The batteries alone will cost more than the item. AA batteries (1.5-V) will not fit into the vacuum. China or where ever it is made must have 3-V batteries. We don't. Didn't get to try out machine due to battery situation, so I can't comment on that. I do not think this product was intended for sale in the USA. Maybe you could try the USB version, but from what I have read they don't work very well.........

Good for computers.

Cant say I used it for its original purpose - cant really say if it is really cleaning keyboards. but I built out of it a kitchen smoker. that cost around 70-100$ ... for that it is just great!
