Long Range High Power Green Pointer,Rechargeable Pointer for USB,with Star Cap Adjustable Focus Suitable for Projector,Camping Hiking for Night

I got my molecular model kit today, it came super fast! I was really stressed because I have a chemistry test tomorrow and I couldn't nail down the concepts. After working with the set it all just .... clicked! I'm so grateful!!!The set is really well designed and very high quality. Really nice presentation, fast shipping, Amazon came through!Thanks for the help in getting my to understand Chem 101 !!!

I use for waterfowl hunting, for fellow hunters in the blind to help me accurately spot fallen game (before I send my dog) to make for a more effecient handle/retrieve. I have to have something visible during the day at 200 yards +. This clearly is, as I can see the green dot against vegitation during the day for well over 200 yards+. In lower light settings you can very easily see the actual beam if that's important to you (it's not to me but underscores the power).

The unit I received is complete and it’s fit-and-finish exceeds my expectations.The gears are clean and mesh well; bearings spin freely and mate properly with other parts. Most importantly, this extruded features a replaceable Bowden coupler.The included instructions (exclusively diagrams) are a nice confirmation for those of us that are familiar with 3d printers; users that are less familiar should consult YouTube to avoid incorrect errors. Remember to tighten the grub screw.

I ended up returning this item as it was smooth where it should have had teeth. It would not have worked for what I needed.

I’m very happy with this suture kit I received, I learned how to do some basic suturing in a class once and I wanted to practice a bit more. I’m hoping that with this kit, I will be able to prepare enough to be able to handle a possible emergency situation. Great!

I've wanted a molecular model since middle school. I need one to help my students and wanted a good kit--and it lived up to my expectations.The kit includes enough atoms to make any type of structure. The double bonds have a great length. They were easy enough to take apart, especially with the included tool; all the molecular model sets are easy on your fingers!I’m going be using this all the time as a tutor. It helps so much to have a good visual considering books can only show so much of a 3D structure.

My molecular model kit came in the mail exactly as described after just a few short days.As a high school science tutor, I've found using model kits like these can be very useful in understanding complex organic chemistry concepts such as chirality. Its really great to see something finally click for a student when they can touch and hold something in their hand, instead of just seeing it on the page. If you're studying organic chem and aren't utilizing a 3d model kit like this one, I'd recommend that you try it out!

Good
