We received this item in a timely manner and it was precisely as ordered. Thank you so much. We’ll order from you in the future.

This really is a fine and reasonably cost Ph Meter. It’s compact and ruggedly constructed. My intended use is for occasional checking on solutions. I was a bit shocked that the meter needed calibration options. (This really is my first such device nevertheless) Even a relatively little quantity of such options was nearly. Not complaining, as the seller was extremely useful but I just was not knowledgeable concerning the require for these options. Meter has worked as intended and given the outcomes expected and needed.

It was a bit slow for what I needed, which was to measure the alkalinity and ORP with the water from my water machine. For the cost it was fine.

HYDROMETER – ALCOHOL, 0 – 200 PROOF Review
It’s been 6+ months since I bought 2 of these meters but I’m now giving them a good rating. My initial use of these hydrometers was producing readings that seemed inaccurate. I’ve just recently tested them with 190 proof grain alcohol and precisely controlled amounts of water/alcohol mixes. Both are a bit off but are well within the tolerance of what they are needed for. One of the two reads 4 “proofs” high and the other, 6 high. For anyone that might not be familiar with using this type of meter like me, you’ll find that using a graduated cylinder that is taller than the hydrometer very helpful. There must be enough room for the meter to float plus an inch or so. Trying to measure the alcohol content from the liquor bottle may not be the best method to get an accurate readying, as sensible as that may seem on the outset. You may also find that removing the contaminants from the test liquid would provide better results. As for the hydrometers, they are a good value and work well if you can validate them yourself and can accept a few points of tolerance in the readings. Don’t buy one, buy two.

Celestron 44104 500x Power Advanced Biological Microscope Review
After returning several different styles of Celestron microscopes this is a keeper. High quality and easy to use. I did notice the bulb attachment does get hot and it has a strange “burning” smell to it but as long as you do not use for long periods of time it should be ok. The other option is to use the mirror as a lighting source. This is strong and sturdy (has a good weight to it). Highly recommended.

This is an amazing microscope for the price. I looked at other microscopes and similar ones start at $300. It is actually just like the microscopes I used in college. Great for those who want a good microscope but don’t need a fancy expensive one for more serious use. Very solid and durable. Excellent buy.

We purchased this microscope for exploring freshwater pond life with our grandson. Overall, it is a good value for the price. Our only issue with the design is the eye relief – which is way too short. There is no way to view the entire field – even without glasses. So we have to “move our eye around” to see the full field. With respect to quality as received, the packaging is very good, and the shipment arrived in perfect condition. We did note many “specks” in the field of view during our initial use, though. So, we inspected the main tube, and found the inside walls were literally covered with some kind of dust. After carefully removing the objectives and the eyepiece and cleaning them AND the inside of the tube, we have “speckless” viewing. Also, the mirror was not centered below the condenser, so we disassembled it, straightend the mirror bracket, tightened the rivit end of the mirror “stud” and opened the split end of the stud slightly to snug up its fit in the micrscope frame. Finally, the electric illuminator would not fit in the microscope frame, and we needed to close up the split end in that part’s stud just a bit. We’ve noted earlier comments about the heat generated by the illuminator, and we agree. We’ll stick to using the mirror and a separate lamp. So, now all is satisfactory, and given the price, power, and features, we are O.K. Our next updgrade, though, will not be a Celestron product. Probaly either Leica or Zeiss.

Just got this microscope yesterday. It’s amazing. Originally I had planned to spend more money on a scope with 1000x magnification power, but when I learned that this one could be upgraded, I decided to save some money and avoid the difficulty of dealing with oil immersion. I am very impressed with what you can see at 400x and 500x, and with such clarity. Also, the mechanical stage is great. I didn’t think of the mechanical stage is a deciding factor when choosing a scope, but now that I’ve used it I can’t imagine not having it. I want to give this product 5 stars, except that, as others have said, this seems like it could be a fire hazard. I actually feel very fortunate that I had read the other reviews that mentioned this danger, because otherwise I probably would not have taken any precautionary steps. Because I read those reviews, I chose to put my microscope on top of a cork coaster when using the lamp. Sure enough, when I moved the microscope aside, you could see that the coaster had started to become d iscolored under the lamp! That could have been my table. Other than that, the only other complaints I have is that this does not come with any blank slides, and the lamp does not have a switch, but these are small issues that do not affect my rating. As long as you’re careful not to leave the microscope unattended when the lamp is on, you won’t be disappointed.
