Rechargeable Finger Ring Wireless Presenter Clicker for PowerPoint, Keynote, Mac, Laptop - USB Presentation Remote with 2.4GHz RF

I have been using this in my classroom for a few months on the Bluetooth setting with a MacBook Pro. The charge lasts a long time. I last plugged it in during September, and it's early Nov now.I use it halfway down my right pointer finger and press with my thumb. The loop circumference is a little too small for me to wear it like a ring as I would like, and the diameter is not adjustable at all. The diameter is about 3/4 of an inch.

I am a middle school teacher. Since the day this came promptly in the mail, I have used it every single day all day long. I wear it constantly. It was easy to set up and it is very comfortable to wear. I love, love, love the laser pointer too. I had it to my students frequently and ask them to point at various slides to prove their knowledge (find a verb, where does the decimal belong, etc...) To be able to not be tied to the SmartBoard or my laptop is THE BEST part. I can be out and about helping students and advance my slides. It works with PowerPoint, Google Slides, Smart Notebook pages, and more. My hands are free to hold the 1,000 things we need at a moment's notice...pens, nurse's notes, Expo markers, etc... I have told everyone I work with about this and they all love it as well. If you are a presenter of any type, you have to get this. Best tech product I own!

I needed a slide advancer for class that would work with Google Slides, as that is where I build all of my classroom presentation slideshows (for convenience).I saw this slide advancer while searching through some far more expensive styles. I love that it can't go onto my finger until I've removed the computer plug in, and that when I've removed it from my finger, I am highly likely to remember the computer plug in because of the gap in the ring. (So far, I have not left the room without my slide advancer or the computer plug in for it. That's a huge difference from the other three I owned before that all were lost to classrooms when I left them behind and someone else picked them up and took them. :/)The battery charges quickly and stays charged for a while. I only teach two classes in person, but the advancer has stayed charged for several weeks at a time with regular use. (I am good about turning it off when not using it, which makes a big difference. But I think it's much better batter than I had anticipated.)It has great range for the classrooms I teach in, which aren't huge. The laser pointer works well, and I can point and advance slides from anywhere in the classrooms I'm in.

It’s a good product; the battery lasts a long time. I use it nonstop from Monday to Friday, and it's very lightweight.

Pros:Connected easily with both RF and Bluetooth to a ThinkPad.Noticed no lag when using Bluetooth.Nice and compact.Simple. Only three buttons, forward, back and laser. My old presenter tried to be a wireless mouse as well. While occasionally useful, it was to easy to hit the wrong button during a presentation and go into the mouse mode. This would end up disrupting the flow of the presentation.Finger ring: I use it for lectures where I go back and forth from the presentation and a white board. With my old presenter, I often set it down while writing on the board. This led to having to look around for it when I returned to the presentation. This is no longer a problem as I can keep it attached to my hand while using the board.Cons:The design of the dongle storage, sticking into the finger ring, means it has to be removed to use the presenter. That means that if you are using Bluetooth, you still have to remove it. If I wanted to constantly be dealing with a dongle, I wouldn't have purchased the Bluetooth version. At some point I will probably lose the dongle and have to make use of the dongle replacement policy. For now, I keep it in the little bag that came with it, but it fell out of that the other day.Since is sits in your hand vertically, the arrows are up and down instead of left and right like most presenters. The down arrow is forward and the up arrow is reverse. That is the way PP uses the arrow keys on a keyboard, up or left go back and down or right go forward, but seems counter-intuitive during a presentation. It took a short while to stop pressing the up arrow to advance the presentation. Once you are used to it, it is a non issue.Neither cons are enough to knock it down from a five for me.

I am an instructor for a technical college. I loose my normal clicker (presenter) like 25 times a day. I set it on the podium or the white board or the table or a students desk..... it was getting pretty annoying. I found this presenter online and decided to purchase it.I really like the rubber ring for your finger. It will accommodate any finger size as the opening is rubber and can be put on any part of the finger. It is a little uncomfortable on the very base of the finger or thumb. I use it right in the middle to be honest. Very comfortable there.There are only three buttons too. fwd, rev, and laser. You can set it to be pageup/pagedown or left/right if needed... but it defaults to the one I use anyway. The fwd button is in the middle, which took a day or two to get used to, but I did get used to it. You can hold down the buttons for black screen, but I dont ever use that function. Still nice to have. I really like it. Very convenient.I would also like to say its nice just being able to not change out the batteries too. My old clicker went through a lot of AAs, but this one I just plug into the USB port of the computer. One less expense! It comes with a small microusb charging cable, which you probably already have a couple of. It also comes with a nice bag (which is too small) and the USB dongle fits right where your finger goes so you dont lose it when not in use. Pretty handy in my opinion.Anyways, I'm very happy with my purchase and the school will be buying more of these soon for all our instructors. A wise purchase for people who give powerpoints on a daily basis. And as a bonus, it makes me feel like Dr. Strange when I use it. Who knows? Maybe a teleportation portal will show up one day! LOL
