I was so excited to order this product as I have been wondering about my portion sizes. I immediately found batteries to put into it, only requiring 2AAA batteries. It turned right on, the buttons are wonderfully sensitive. I compared measurements to candies I was able to find. It was spot on for grams, and 0.01 oz off from the weights, but that's close enough for me.

It seems delicate, but it has held up well considering my partner had unwittingly and heavily placed items on top of this. I take great care of my items so how he treats things is alarming to me; this is something I intend to baby. I am working on drastically changing my diet to better compliment my work out regimen, this is what I have been waiting on to help me determine proper portion sizes.

Even more exciting, my partner baked his OWN chocolate chip cookies instead of bugging me to do it for him. How many women can say they have that lucky anomaly occur?! He was excited to weigh his measurements as he read some chefs blog that said recipes turn out better when you do so.

I would buy this product again, as so far it's been excellent. I received this product in for free or at a discount in exchange for my honest review. I rely on amazon reviews when choosing my products and find the reviews I post to be of importance to assist other amazon customers with their purchase choices. I do not get penalized for a bad review just as I am not rewarded for a good one.

If it wasn't for the unresponsiveness of the buttons, this calculator would receive five stars. Although the calculator is priced well, has exceptional functions and user-friendly layout, the unresponsiveness and 'gummy' feeling of the buttons take away from its overall usability.

I love this case but had a problem with the buttons. I couldn't turn my phone on and off so I cut out the on/off button so it would work easily. I left the volume +/-  as is because I don't use it as much. Otherwise, this is a really nice case. Galaxy Wireless was great too. Fast delivery !

Nice and secure, well built, buttons line up perfectly!

Buttons are really easy to press. A bit larger than what I hoped for, but I guess that comes with the extra protection.

I have to take a star off for the ease with which these switched can be accidentally triggered. They are very easy to press. When you're reaching to the back row of buttons, it's too easy to drag a heel across a front row button, which is fairly disastrous for me. However, the form factor is perfect, and the programming flexibility is excellent--the switchable pedal is great.

The material is very stretchy so it will fit almost anyone unbuttoned, and for me the small is a great fit; perfect for my arm length and torso length as well. However, when I button all five buttons, the bottom button stretches and leaves a hole which looks silly. So, I leave it unbuttoned and it leaves a sort of v shape which isn't awful looking but not how I would like it to be. I am 145Ibs and 5ft 8in tall so keep that in mind. All in all I love wearing it, preferably unbuttoned though.

I was a little skeptical at first, after reading reviews about there being one big button. But I have so far actually loved there being one button. The tracking is excellent for a mouse in this range, just what you would expect. The only complaint I have is the scrolling, I would actually have proffered there being a scroll wheel, as I can't quite get used to the scrolling. But again, it's one of those things you have to try for yourself. The packaging was very secure, and didn't feel clumsy. Overall, I'm very pleased with this purchase. And as always, Amazon Prime pulls through and gets it here quickly.

The short review is I love these and they are great for the money. The battery life seems pretty good, but be aware that the buttons on these units are very sensitive. It's very easy to change the channels on these just through handling them. I keep them in a Royal Crown bag hanging on the light stand, you can't see the lights through the bag. I've unknowingly changed the channels and went nuts trying to figure out what my problem was because I didn't realize that I hit the buttons while placing the unit in the bag. Just  a heads up.

I was pleasantly  surprised by the look and fit. The only problem I've noticed (and it's minor) is how it makes by buttons ultra-sensitive. With other cases I had the opposite problem where I would have a hard time changing volume, locking the screen,  etc. Now it's easy for the volume to turn down all the way when the phone is in my pocket.

This may be the most comfortable fitting mouse I have ever used. The surface has a slight texture to it (nothing much, but just enough that it isn't slick). It is super responsive and that can even be changed with the Razer software. In fact you can change a few other settings too which is really nice. My only gripe are the buttons on the side. I didn't take off any stars as I think this is just a preference issue. The two buttons for your thumb, for me are a little awkward. They are somewhat flush with each other with hardly any gap between them which makes me pause for a split second to make sure I am pressing the right one. Maybe once I have used it a little longer I won't have this issue as I have only put about 10 hours use into it. Overall though - I think it is great.

I have had problems with double-click when only one click has been pressed. The thumb buttons are perfectly shaped and positioned.

Sounds great. only small problem is the on/off button is not sensitive enough i.e. you have to push too hard and it is too slow.  that certainly wouldn't deter me from buying it. also, it fits and feels so well that I forget I'm wearing it.

I first bought the Anker 2.4G Wireless Vertical Ergonomic Optical Mouse, but I couldn't get used to it.  The buttons were not easy to press unless my whole hand was wrapped around the mouse which made it hard to maneuver. The buttons of the Delux M618 mouse are much easier to press, and I can hold and move the mouse with my fingers instead of my whole hand (I removed the hand-rest extension piece).  This makes it easier to position the cursor accurately.  I also like the position of the "back" and "forward" buttons.  It makes more sense because of the way the thumb rests on the mouse.  I got used to the mouse the first day I used it.  After 5 days, I'm so comfortable with it that I don't think I'll ever go back.
