I was expecting an actual vacuum pump, this is basically a solder sucker back end attached to a hollow soldering iron in one piece.  The diameter of the end of the tip was too big to fit on the solder joint for the small electronics work I was trying to do and I was having a hard time trying to desolder an IC with it.  I kept switching between a regular solder sucker, braid and this tool and ended up reaching for the wrong one hot end first.  Three weeks later the burns on my hand are finally mostly healed.

I returned this, didn't have the suction I was hoping for. Got a dirt devil instead

this was not useful at all. I really feel that I was robbed.. it doesn't fit into anything! I lost my money! It was supposed to fit into the TMS 3 CFM Single-stage Rotary Vane Vacuum Pump R410a R134 Hvac A/c Air Refrigerant but IT DOESN'T!  I lost my money!

This vacuum has good suction, the cord rewind works fairly well, the metal wand is nice, but the rest is very disappointing. The attachments are an absolute joke! The floor nozzle has a retractable brush in front, and a squeegee in the back. There is no way for dirt to get under it to be picked up. You basically have to pick up the nozzle and put it down over whatever you want picked up. With the brush retracted, the nozzle fits flat on the floor causing the same situation. The rollers are at such an angle that you have to lean down to get the nozzle to roll on the floor. The crevice tool/ dusting brush is about 2 inches long with a folding brush not much bigger than a toothbrush. If you are buying this for a replacement vacuum, save your old attachments, or be prepared to buy real ones.

the pump has used two sets of 4 totaling 8 brand new Professional D Duracell batteries to finally get this blown up. Regardless of the battery usage, the pump kept slipping out of the hole while blowing it up possible reason for so many batteries, and there seemed to be air escaping from the cap of the chamber as well. this was NOT what we expected for this price, I am hoping this was just a fluke and one time issue however I will need to return this item

The vacuum pump I bought had a 1/4"/R22 fitting, so this helped me evacuate my car's AC system. I wish I had a convenient way to store it, but that's not their problem.

I bought this because it had a hose and a pump, but the info did not say that gravity feed hose and the pump hose were different, and different dimensions.  I cannot use the pump hose, because it's a special skinny hose that did not attach to my previously-installed hose line that leads to a drain.  So I am using the gravity feed hose instead.  If I had known this I could have saved money by not buying the model with a pump.

Product has terrible suction. I wasn't expecting a whole lot power from a 12V, but this thing barely picks up anything

Don't make the mistake I did.  I thought this was a standard Dust Buster size.  It clearly is NOT in that category.  This is about one-fourth to one-third the size of a Black & Decker dustbuster.  This is a toy. It sure makes a lot of noise, however. But if you want a real vacuum, look elsewhere.

I really wanted to love this vacuum, but.

I was super excited to receive this vacuum because of all the endless fantasies it would fulfill.  I was tired of the standard vacuums with short hoses that would not reach in crevices, and this vacuum was to be my savior.
I carefully unboxed this vacuum, which was packaged well, and took to testing this baby out.  Man, this thing has great suction.  My test of vacuums is how long it takes for my 8 year old to vacuum the family room.  My little boy was working up a sweat just pushing this thing a few passes, so I took over.this thing was a beast to vacuum my thick berber carpet.  My wife refuses to use it as its just too hard to move.  Suction on the tile and short carpet was much more reasonable, but stay away if you have thick plush carpet.  The telescoping wand excellent, and was easy to use to reach into crevices.  The attachments were easily attached and stayed in place with use.  The long cord is plenty for my large room., and the HEPA filters are good for the allergic.

Now to the bad.  The machine topples over any time you try to move the machine.  They should have designed the hose in front instead of coming out the top.  This thing is loud, which is conducive to the great suction, but I felt like I had to wear my ear plugs to prevent my ears from ringing like I just came out of the night club.  The retraction contraption is horribly weak, and nonfunctional 50% of the time.  The overall machine appears sturdy, but the wheels are made of cheap plastic, and I anticipate them breaking first.

All in all, this would be a good machine for a small house with short carpet.  Larger homes or thick carpet and this vacuum is a no-no.

The description says it has a Battery-operated pump. It does NOT! I even bought the batteries that it said was required to operate the pump. I am going to try to return it for one that does have a built-in pump. I did not inflate the air mattress because I do not have a pump, but the material feels very soft.

I wanted to use this as a vacuum in my dorm and the price was great so I thought I would give it a shot. It really didn't pick up enough dirt and it wouldn't pick up any hair at all. I have low pile carpet so I thought it would work - wrong.  I ended up buying a regular bagless vacuum and this Bissel featherweight is sitting at the bottom of my closet as a back up (at least it doesn't take up much space.)  Bottom line: if you need a vacuum, buy a real one.

I must admit I've never owned, used nor witnessed any hand-vac cleaner in action prior to purchasing this product. Based on the reviews, I figured that this was the machine for me. I was very excited to be able to clean conveniently and not having to haul out a huge vacuum. I won't say that this product disappointed me, but it just didn't quite live up to my expectations (which, arguably, were probably too high in the first place).

In no particular order:

1. For the love of me, I couldn't figure out how to get the machine off the base and nothing in the mini-manual gave instructions on how to do the same either. Finally, I read a line giving instructions on how to place the machine back into the charging base, and I did the opposite to free it. Very minor issue.

2. While opening out the machine to figure out how it worked, I was a little surprised that the whole mechanism isn't a bit more complex. I wasn't expecting a cup to come flying out of the container when I opened it. I was so confused (having only dealt with vacuums with bags all my life) that the dust was expected to be collected basically on the open space at the front of the machine. I was shocked that there wasn't some kind of collecting canister that we empty, wash and replace. I was also shocked that the filter holder was just meant to fit snugly in the machine without any way to secure its position. I would have thought that the immense sucking pressure would require everything to be snapped into place.

3. This machine is incredibly noisy. It's almost embarrassing to use it. Such a small thing with such a loud voice!

4. I do love the colour, love the build.

5. As I stated before, I have no prior experience with hand vacs, but from that first time I used it, I didn't feel like it has the same amount of sucking power as my hose vacuum cleaner (without all the extensions, that is), which is understandable, I guess.

6. I can't seem to get the clear extension attachment to snap into place exactly in line with the main nozzle. I am a bit afraid to apply too much pressure in case I snap the hinge joint.

I'll try to play around with this more so that I can get accustomed to it. I hope I helped some other newbie to the hand-vac world.

I bought this to inflate my brother's air mattress as the ad said it would fit any connection. It doesn't. I hadn't seen my brother's air mattress before purchasing this for him. However, it doesn't work. This is pretty small. And the opening for the air mattress is more vacuum hose sized.

I can't really complain about what it does, but my expectations were that it would be as much of a vacuum cleaner as a steamer. That's sort of true, but the roller must be on for it to vacuum. I don't like that since I have new cork floors that should not ever have a roller-brush vacuum. But it does pick up nicely.

The reviews about cheap parts is easy to see. Mine hasn't broken (yet) but there are lot of places where I can see it probably will eventually.

First the good
1. The mini circulating pump is strong
2. Size is small and does not take too much space

Now the bad
This is not a wave maker. Its a water circulating pump. It took me 3 to 4 tries to make the pump turn in the right direction. First time I started it it was sucking water instead of pushing water. I connected it to a wavemaker board and sometimes it works in the right direction and sometimes in the opposite direction. Its just the first day I have received the product. I guess I should have been more careful when I saw the price to be so low.
Anyways it did not meet my purpose. I have to return. I guess Amazon should change the description on the product as its mis-leading.
