Kokuyo Power Point Operation for Finger Presenter Obsidian Kokuyoseki Ela-fp1

A small red LED illuminates on the receiver to let you know you have pressed a button. That is a nice touch. I have had no issues with it. It has worked perfectly. The only issue is its' "ring size". I have small hands and it is way to small for my finger that would make it unusable for me. However, I discovered that if I place 2 AAA batteries in the ring and allow them to gradually stretch the ring outward, it will fit just fine for a while after the batteries are removed. There is the possibility this pressure might cause the rnot ing to break at some point. Mine hasn't. I just leave the two AAA batteries inside the ring until I go to use it. Then it seems to fit jusdon t fine. Otherwise, this is a very nice presenter.Update: The presenter worked flawlessly for almost 3 years. Actually, it still works but the ring broke. This is no doubt due to my stretching it apart with 2 AAA batteries when not is use to make it fit my finger, I will probably buy another one since I cannot find anything else this small that works for me.

works as advertised; the only problem are the rings - there are two sizes, small and tiny, and the plastic is too hard and does not really bend.

If you ever have to give ppt presentations, this is a MUST have! It slides onto your index finger (that's what I use) and then is positioned so that you may press the next or back button with your index finger. The set up is fast and easy - plug the USB dongle into a laptop/device, turn on the "ring" and you are all set.Some cons: would prefer to pair with bluetooth as opposed to the USB dongle (if you lose the USB dongle the device no longer works). The "ring" is a bit small and the second "ring" is even smaller.Pros: small, easy to use, works like a charm, reasonable price!I gave one to the president of our company and have now ordered for our entire team.

I love the size of this unit as far as the clicker goes. The two rings sent with it are quite small. I'm a guy but for a guy I have very small hands. Even with small hands, I found the largest of the two rings a very tight fit. I actually ended up taking the small ring, cutting away the ring portion (keeping the battery mount part) and gluing on a silicone ring that fits my finger. That part worked well. What I have not decided yet is if this unit has enough output to be reliable. It appears the battery that came with it was pretty low on charge - probably been sitting in warehouse too long. Found that if I had it in wrong position where my body was blocking signal between transmitter and receiver, it wouldn't trigger. This is supposed to be an RF unit, not IR so some blockage shouldn't matter. The annoying thing is that I'd hit the clicker, nothing would advance and I'd tap it again then, if I moved my body so it had better reception, it would advance 2 slides. Because the problem seemed to get progressively worse and I then discovered the poor condition of battery, I'm hoping that a fresh button cell will eliminate the problem. If it does, I think I'll like this unit a lot. My goal is to find a compact clicker with good RF coverage that easily palms in my hand. We'll see. The attached photo shows the unit with my modified silicone ring attached.Followup - Got new batteries but, unfortunately, that didn’t improve things. If I put my hand behind my back so my body is between the clicker and the dongle on computer and try clicking, it works if I’m within 5’ of laptop. Farther than that the RF signal from ring is apparently too weak. I have another RF clicker that performs flawlessly in same situation at 20’ or more so I’m convinced this little guy is just not very powerful. I still plan to try using it because I like the size so much but will have to be very mindful of possible interference.

I give presentations frequently to medical students and physician groups. I like to walk around the stage in order to keep the talk more interesting. This is so much more handy than the large slide advancers that are usually offered at a venue. Your hands are free to use for natural gesturing and it looks like the slides are advancing perfectly on cue without any distractions.

As a pastor I use this weekly and it works great. I like to create my own slides and move through them whilst preaching. This allows me to do so whilst still being able to hold my tablet or my Bible. It doesn't fit like a ring but still is better than a full sized switcher.

Fairly recent purchase but I like how it works. I've ordered extra batteries - 10 pack for $5 so reasonably priced. I'm replacing it because I talk with my hands. Last week, I dropped the presenter I had and it was in 3 pieces (different brand but it took a beating). I like that I can talk with my hands and not worry about dropping the presenter!The only small improvement that I would make is the bag is black. That makes it difficult to see in the briefcase. A brighter color would make it easier to spot.

I have to get used to this gadgety gadget. But I love it. I'm glad operation is self explanatory, because the instructions were in Japanese!
