Elecomusa Avis 

I placed an order that was never handed over to the carrier. On messaging customer service I was told a new order would be shipped. Had to chase for a tracking number was then given a tracking number which on investigation wasn't related to my order or address. This all played out over the course of a month.
Something very strange is going on with this company. Avoid at all costs. I'm currently $250 down and have a very annoyed client who I purchased for...

I did not receive the trackball I ordered and Elecom, USA is not returning my emails. They claim it shipped, but it did not. Also, I was told they fulfill through Amazon. I contacted Amazon and they confirmed Elecom orders are not fulfilled through Amazon, so that was a lie.

At this point I realize I have been scammed by Elecom. The only form of communication with the company is email and they do not reply. I guess it's going to go to the BBB or the FTC for scam/fraud investigation.

They took me for $150.00

They claim that my order was delivered.
They cannot provide us with the details of the delivery, like to which porch it was delivered to. or if it was actually delivered. All they keep saying it is delivered and they wash their hands of the matter. Our ring camera does not show any delivery to our porch or even to the row of houses we are situated in. so there was no delivery to our short street. we have 6 houses on it. so it is not difficult to put it at one of the other houses. Shopify says it was delivered at 6pm. my email alert says same thing, then they tell me it was delivered the next day at 9am. camera still shows nothing both times. unless they used the invisible man, but then i would at least see my parcel. i looked up and down street checked everyone's porch and nothing. i checked a few minutes after i received the notification. we do not have porch pirates in our area due to a very good active neighborhood watch.
The Issue i have with Elecom is that they just do not care, they got their money. F@#k the customer.
So beware, you order and pay, you may never get it..
So i cannot even give a review of the product because there is none....

Huge is not at all Huge
The new trackball I bought was from Elecom in Japan and though the name of it is HUGE it is not made for huge hands; not even for medium hands. It is perfectly sized for my little 9 year old girl. A piece of foam to make the hand rest larger and it almost works for my size 7½ – 8 glove hands.
Contrary to what is very often mentioned on YouTube the original synthetic red sapphire bearings are not bad. In Low sensitivity setting it is perfect for a 24” monitor full 1080p HD, just a push on the ball and it rolls from one side of the monitor to the other, in Mid setting functions great with a 4K monitor, so believe in High setting it will be just what 8K monitors need. The ball runs smooth, the scroll wheel is OK, right- and left-click, forward and backward are functioning without programming them.
Having software running to be able to use the 3 FN programmed is not for me, should have been made so they could be programmed without having extra software installed and running.
All in all an OK trackball for small hands from factory, had it been tilted a bit to the right side (35 - 40 degrees) so hand would be resting better but will have to use it a week or so to see if hand can get used to the slightly new position. After having used it a while I see that it needs to be tilted at least to 45 degrees in order not to give carpal tunnel syndrom.
Had they called it Trackball without the word HUGE, I would have given 2 stars, as big it is, almost as big as the perfect Logitech TRACKMAN MARBLE FX T-CJ12 and Logitech Cordless TrackMan FX M/N RA17 but having that name and fitting a hand size X-small – small that made me buy the trackball and now I have to modify it in order to use it without getting pain in my wrist.

Follow up to review of the Huge trackball.
Still smooth and great to work with. Those mentioning it does not roll well must have received second quality as this one is as smooth as the best of the old from Logitech that unfortunately no longer are made. It is very small for a ”HUGE” but when placing it on a tilting material it is OK to work with for longer periods. No trackball will ever come up to the perfection of the old Logitech T-CJ12 TrackMan Marble FX that I could work with continuously 12 – 14 hours without wrist pain. Wish somebody would copy that. It was not bigger but made for bigger hands, it was corded but should not move around but stay firmly so no problem there.
Conclusion: the HUGE is not recommended as though I find it is the very best available trackball made now it will give you Carpal Tunnel Syndrom after using it a relatively short time.
