I gave this three stars a year ago and I am upping it to 4 now.  This one works amazingly better than the one I purchased a year ago.  The key to using this is adequate pumping: if you are not pumping it 12-15 times it is not going to mist.  Also be aware that the useful life for this item appears to be about 18 months tops and you will have to buy another one.

Bought this device as a replacement after learning that improvements had been made with an older version that I bought last year.

My old one still worked, but I got tired of it falling off the refrigerator at least once out of every 3 times that I touched it. I wish I was kidding. On the bright side, despite the number of falls, it never stopped working.

The new model uses 2 smaller magnets instead of 1 large one -- and this seems to work. I've used the new one several times a day for over a month and it has never fallen.

Most of the improvements are listed in the product description, so I'll comment on just a couple here. As noted, there is an on/off switch, but the device uses so little power that it can be left "on". To illustrate, I left my old one "on" most of the time, and it's used the same off-brand battery for over a year.

Also, the loudness of the alarm has been reduced. You can still hear it from the next room, but it no longer causes a heart attack. Also, when you're setting the alarm, the new unit doesn't beep at all. The old would beep (loudly) for each minute/second that you set.

It looks like most of the 1 and 2-star reviews are complaints about the older unit ("loud alarm", "beeps every time button pressed", etc.), and these have been addressed with the new model.

I ordered the SP715A. I received the newer version 780-715 of this control board. The newer one has a feature that eliminates the need for the fame sensor. My furnace has never worked better. The new control board has completely change the way my furnace operates. Instead of the fan coming on, then lots of clicking, and then the main burners lighting. The entire process is instant. The thermostat calls for heat, the fan comes on, one click or two, the main burners light, the furnace is on. I am so glad I bought this. My old one was still good, my exhaust fan motor assembly went out. I bought the motor, control board, high temp tubing. After I got my furnace working, better than it has ever worked before. I even bought a fancy new thermostat. My furnace should be good for another 30 years.

I purchased this one because due to my old one went out at a year old and mfg won't Warrenty it. It was a expensive book shelf holder now. I love this one it works just as good and had more features than the old version does.

As the title says I wish I had bought this one years ago instead of buying cheap ones once or twice a year (that are not particularly cheap in price). I wasn't sure I could justify paying this much for a garbage can, but it's worth every penny. The butterfly design is pretty genius and its compact size doesn't take up much room. It seems to be pretty airtight because I've never noticed any smell even when full. There's a lever in the inside that allows you to keep it open continuously which is great when I'm cooking and want to just pitch something as I go. Also, with the bags - you can purchase them through the website but they're kind of expensive. They don't seem to be any better quality than the ones you can buy in a store. We use the plain old Hefty tall bags (I thinks it's 13 gallon) and they fit just fine. Save your money and buy those. Also, it's pretty easy to clean or change the bags. The inside lifts out which makes changing the bag a cinch. Stainless steal will show some water spots or drips, but I keep those stainless steel wipes handy and they just wipe right off. Have had about 6 months and looks and works just as well as when I bought it.  Would have never thought I would actually have a strong opinion about a garbage can.

Buying this product was just one of the very few good decisions I've made this year. Bought and tried another brand and finally had to get my money back. I bought this one for about $10 dollars less and got twice the product. Very easy to program and easy to use and works better than I expected. Don't be afraid of this item.

I bought as a gift because I love the one I bought about a year ago!!  Inexpensive, but works well!

I had the previous version without a timer that had a bottom heater which I liked quite a lot. This one is 100 times better! I love the times so I do not forget to shut it off saving on electricity. It also is much more powerful and does a much better job more quickly.

Little to add to the title. It functions better (more suction, longer battery life) than ANY of the others I have purchased over the years. I just purchased a second one as the first one, still in use, was purchased in March 2010 and is as good as new. The number of  Black & Decker units I have wasted money on is sinful. How B&D remains in the business is beyond me. In any case, I highly recommend this unit.

I don't leave many reviews, but I am amazed at how much better this works than the last one I had.  The laptop is actually cool to the touch.  i just hate that i used the other one for almost a year before finding this one.  Great product.

I used it the first day I got it on my chef's knife, the kitchen workhorse. I noticed how much easier to use it was than previous models just because of it's upside down action (you'll see when you get the unit and instructions). You hold the sharpener in your control hand, not the knife, so you can control the pressure, the angle and the smoothness of the pass over the blade. So more control. When I cleaned off the blade and started using it, I was amazed at how much better the cutting was on celery, tomatoes and the hazelnuts that I chopped for cookies. I was impressed. Previous comments mentioned it won't last for years and years because the sharpening blades need to be replaced, but for less than $10, I'll gladly buy one every couple of years if it works this good.  You can't beat the price.

I was skeptical, but this has to be my best amazon purchase in the past year. We had a crazy mosquito infestation in our apartment, leaving us chewed up night after night. I bought this in desperation because nothing else was working. After two nights, the apartment was livable again. I've used it every night for the past 6 months and I am about to order another to leave in the kitchen.

I bought this about a year ago and it was horrible. It would constantly lose connection and start beeping. So I took the battery out and put it in a drawer.

After about a year, I noticed that the software on the Play store had been updated so I decided to give it another whirl. It now connects and stays connected -- and there are no spurious beeps anymore. Works just as it should.
