The HP Prime has a built-in rechargeable battery. My experience has been more battery life out of the AAA's than the HP.Also, you need not drag around the recharging cord. It boils down to what are the esthetics. The HP prime has a much larger set of applications.I use both, but I use the HP prime more ... also, it has an emulator that you can put up on your computer.

My vote is for the h/p Prime. I tried the TI-nspire, similar to the Casio in terms of buttons and general layout, but found the Prime to be easier to use as a calculator. Other than raw programming power (the Prime will win this race, I think), the Prime is designed like a calculator: all the frequently used functions are on keys and that speeds up both calculating and programming. Keys on a calculator use less power than a touch screen, last way longer and in the case of h/p, are really dependable. If your initial purchase is for education, I think the Prime will be a calculator you will keep for use at work. My vote is for the h/p Prime.

The batteries work just great. I've had mine for about 1 month and I use it everyday for 2 to 5 hours. No problem with the display or battery power. It dims the screen automatically, but stays dim so you touch the screen with the stylus or with your finger and the full brightness snaps back on in a split second. In a few minutes it powers off and repowering it back on returns the display to where you had left off. Believe me, the batteries are no problem.

I have two like this, but they're a little different from each other. I remember once I thought one of them was broken because I had just changed the batteries but it would not turn on. Then I realized it wasn't set to play on batteries or something... I can't remember exactly what the issue was, but it was a very "duh!" moment. Otherwise just get another one - it's $6 crap from China.

Apparently not all of them are made in China. I just received this DCK286D2 combo kit a week ago on Wed., Jan. 21, 2015. Sold and shipped by Amazon. Both the DCD795 hammerdrill and DCF886 impact driver state clearly on them, "Made in Mexico." Outside of box also clearly states, "Made in Mexico." Both of the batteries state they are made in Malaysia. Anyone else get any made somewhere besides China?

I guess Amazon has the batteries for this device. I just know I can't buy them just everywhere. I don't know why they didn't use a AAA battery. I think they are thin enough but well...they are the designers. I don't live in the U.S. so maybe that's why I can't get a hold of this model of battery so easily.

Tl;dr- China, and maybe.I bought this for my g/f and she and I are both pretty happy with it, but it isn't like buying a hakko or metcal where you expect it to last until the sun dims. Having said that, when I cracked the heating element it was quick and easy to find parts both locally (Fry's) and online. Whether that will be true in ten years remains to be seen.

I saw your picture with the different tops fpr the different varities of batteries. However on the internet, they do not show the tops in the ads. there are two different pre-charged Duracell batteries. One has a yellow/gold band between the coppertop band and the bottom Duracell label band. One does not. Coincidentally the ones that have the band are usually cheaper like the ones on this page. (Search Duracell Pre-Charged Batteries on Amazon) I have the some of the ones that don't have the band, and they work very well, and have for months. I wondered if this was also a clue as to whether they were made in Japan or China. I saw your picture with the different tops fpr the different varities of batteries.

It's cheaper since it's the latest offering from Casio and they're trying to encourage current owners to update and prospective buyers to get the model that looks more "current". In some Asian countries you can still find the FX-991MS selling for $30 USD, but any newer models are around the $20 mark. In case you were wondering, the natural textbook display can be turned off and the calculator operates exactly like the FX-991MS. I use all of my Casio units in non-textbook mode for speedy entry.

There is no difference in functionality as far as I can tell. The only thing that I can think would be the difference would be the market in which the device was originally intended or perhaps the year it was manufactured, but I could not even find the 400l on casio's website when I was looking at purchasing mine. I purchased the 400l because it was significantly cheaper than the straight 400 model when I was looking. I would say pick up the cheaper of the two if you are trying to decide between the two. The one I purchased has worked magnificently, and has done the job I needed it to. I purchased mine to for use in my upper level math and electronics courses at school (University), the only caution I would take is to make sure that your school (assuming that is what you are buying it for) allows the use of CAS calculators. Some do not, and it would suck to purchase such an advanced calculator and not be able to use it on tests or in class.... Though I guess it would still make doing homework easier.

the latest version of this calculator uses a single lithium rechargeable via a standard USB connector to charge it. however the owner manual for this calculator depicts 4, AAA batteries along with a CR2032 for backup. The newer model though only sports that one lithium. If the one you have or intend to have still uses the legacy battery system for this entire TI programmable line you should use AAA lithium's rather than alkaline. don't use ni-cad or ni-mh. finally, the single lithium rechargeable lasts a long time... AND the calculator even sports a battery monitor. Personally THIS is the battery system I'd be looking for and not the legacy type. the latest version of this calculator uses a single lithium rechargeable via a standard USB connector to charge it. however the owner manual for this calculator depicts 4, AAA batteries along with a CR2032 for backup.

I saw the lower numbered models at Frys this weekend. They didnt have the L117FX/B. I played around with it briefly and the touch screen was more responsive than the HP all-in-one model. All the HP's had Vista and DVD drives for about the same price as the Sony, which had blu-ray and Windows 7. Although I dont think I would use the touch screen much (don't like the smudged screens), I did like the look and build of the Sony. Everything seemed to be built a bit better than the HP. I can't wait for the reviews to come out...

HP Premium Plus from Switzerland had a rough backing. when I purchased again - the backing was smooth. Then I noticed the smooth backing was made in Germany. So, FWIW, the emulsion quality as far as I can tell is the same - but if you want the rough back, make sure it's from Switzerland. However, it "is" possible they don't have the Swiss contract anymore. I preferred the rough back - as did my clients. But again, the quality of the image is the same from my Canon printer. The country of manufacture is on the back of the package, lower left corner.

well, if you shop around at the same places it really doesn't sell for less in the real market, it sells for about the same, but the main reason, just like why the ti-83 sells for way above what it should be selling for considering the software is like 10 yrs old or even older, is that ti has their foot planted solidly in the college market, which in my opinion is really corrupt, because these colleges only use the ti's in the math classes, you can use other graphing calc's like casio, which are just as good, but the schools don't support or give instructions using these other calcs, which they should be, talk about corrupt, wow. the ti-84-C calc is the same as the silver except it has a color screen which is really nice, now don't get me wrong, this ti is nice, and I like it, and this is the calc that you can get all the programming info off the web to program it, the casio fx cg10 is every bit as nice if not nicer (a few extra's on it, and also a color screen) and priced at the same if not cheaper, which you can also use in the colleges, so if you understand calculators you'd be fine buying one of the casio's, either way, they're both great, and I have the three of the casio's calc's and three of the ti's, I kind of collect them, I guess, like a golfer collects golf clubs.............LOL. I even have the HP calc, but you really don't want to buy this calc for school, it's all business and you really do have to fully understand graphing calculators to use the HP graphing calc.

I have an old HP 11C eng calculator that calls for 871B. I also would like to know if these are proper replacement for 871B. Have also used MS76

Go to the HP website. You can do a side by side comparison of the two models. There are a few slight differences that may or may not made a difference to you based on your usage. When I bought mine in Jan through amazon the price was $749. So prices must be coming down or amazon was able to get a good deal, because it cost more at HP.

The HP 4530s battery has been very dependable. I've had the laptop for roughly 2 years and I still get a least 3 hrs. of use on the battery. Obviously how you have it set up - "Power Saver" mode versus "Optimized", screen brightness, when to turn off display and when it goes into sleep all make an impact (as well as what programs/software you're using). It has always met my needs better then other laptops I have previously owned. I hope this answers your question. You should not be disappointed.

I owned one of these new from hp. my battery would last up to 4- 1/2 hours. But I followed the owners manual. And this is the best laptop that HP has made in a while. and If I had extra money I would buy myself another one.

HP quietly upgraded the processor a few years ago, necessitating more power. The current HP12C models (HP 12C, HP12C 30th Aniversary, HP 12C Platinum) use 2 -CR2032 - 3 volt batteries. If the battery door is half as wide as the back of the calculator, it's a later model using 2 batteries. Models from a few years ago use 1 CR2032, while the original uses 3, 1.5 volt 357A (LR44) "button" batteries.
