4.0 out of 5 stars Celestron 100 prepared slide item 44412 listing, July 19, 2008
This review is from: Celestron 44412 Prepared Microscope Slides (100-Piece Set) (Electronics)
Celestron has taken the typical Chinese laboratory prepared slides, corrected many of the spelling errors in the listing that comes with the box and packed the wooden box in a nice printed cardboard box. The selection is more interesting than the three other '100 slide' collections that we have, but the quality of the slides is the same. Only about forty of the slides are duplicates of our other sets, and ten of those are different enough to merit keeping both prepared specimens. I like the wooden box, and Celestron's slide labels are better than the other three sets because they have the slide numbers located at the very top of the label (some sets do not number the slides themselves).

Six of the slides are not what is listed in the printed list of contents; not a cause for complaint since no seller had a listing of the slides when we ordered them. Your purchase may have different substitutions. Many of the slides have spelling errors typical of a non-English speaking, non... Read more

Great for showing the microscopic world to a beginner. Enough variety to keep them interested for awhile. Good companion to go along with a decent scope.

This review is from: Celestron 44412 Prepared Microscope Slides (100-Piece Set) (Electronics)
The slides are of excellent quality and as described. You may not can tell by the picture, but the box that the slides are in is made of wood. I bought this set along with a microscope and a book entitled 'A Guide to Microlife' for my 14 and 16 year old. They really enjoy it and we are making our own slides to add to the collection. If properly handled and stored, this is a gift that can be passed along for years to come.

This little plastic periscope is great for shorter people who might want to see what's on a high shelf or on top of a tall appliance. It's helped my wife a number of times. And it's great fun, too. The periscope is well made and the mirrors are of high quality. What could be better?

This item seems pretty well constructed. It has a larger view area than the little kid ones. My grandson (age 6) seems to enjoy it. You do have to instruct the kids to try and not get fingerprints on the mirrors, so they will need cleaning from time to time.

This review is from: Cstar DM-5 Periscope with Shatter-Proof Mirrors and Wide Angle Field of View (Green) (Electronics)
FIVE STAR ALL THE WAY. I bought this item to have on hand for my Grandkids to play with when they come to visit. Everyone loves it -including me---I am confined to a wheelchair and boy oh boy have I found uses for it, from finding things in my pantry, to looking up under my sink to see how to tighten a loose water valve. Also I can use it to look out the kitchen window to the side to see who is at the door. It is durable and the mirrors are glass and clear as can be. Every one who comes picks it up and starts looking around and over and under things. Attach a tiny flashlight with velcro and you can see under your stove or dishwasher etc. (a spooky thing to do if you are the one responsible for all the junk and dirt and crud you can find there). I wish it were longer, but I love it as is for the kids--and me anyway. Sig

5.0 out of 5 stars Great gift for Mom, June 5, 2009
Amazon Verified Purchase( What's this?)
This review is from: Bushnell Natureview 8x40 Porro Prism Birding Binocular (Electronics)
I sold my astronomy binoculars (too big to be useful, the telescope is easier) to buy my mom - a birding enthusiast - these for Mother's Day. When I got them I checked them out for myself. Great detail, good magnification and field of view, and easy to keep steady. After dark I looked at some open star clusters and found that they are great for astronomy too. Mom loves 'em, uses them almost every day from the kitchen window for urban bird-watching. I plan to buy a pair for myself for astronomy.

Amazon Verified Purchase( What's this?)
This review is from: Bushnell Natureview 8x40 Porro Prism Birding Binocular (Electronics)
My wife is absolutely thrilled with these. She uses them mainly for bird watching. 8 x 40 works nicely for viewing objects approximately 50 feet away. Not too powerfull although it also does a nice job with objects 100 yards away too. Construction seems strudy as well. Would definately recommend.
