Whats up, folks!
Ordered this one from Tmart, I was able to get 5$ coupon from Tmart when they had 5$ coupon giveaway and I missed it, luckily Louis from Tmart was kind enough to provide me with said coupon, yay for budgeteer in me!
Review:
Price paid was 8.99$, the original price on this item is 13.99$.
My unit came in hard plastic box with caliper wrapped in plastic bag, including simple manual in english, one battery installed in caliper, brand new spare battery and small silica gel packet to absorb moisture:
The box is well made, sturdy and with nice foam cushioning/padding inside, caliper fits in nicely, I expected it to come all wrapped in bubble wrap without any box or in paper box at best, Im glad it came on plastic box, because many have reported receiving such calipers all bent and damaged during transit.
Accuracy:
As far as its accuracy goes, Im quite pleased with it, I mean, its cheap, its meant to measure on a regular scale and not on a subatomic one, I doubt anyone will actually use this to measure things as small as 0.0x mm/0.00xx inches, I know I wont measure items this small and Im also sure that such measurements will be highly approximate at best.
For those of us who need to measure things with accuracy up to milimeter, I think this is good enough for such tasks, I bought one to do measurements on my flashlights, especially to measure reflector sizes, lenses, drivers and tail cap dimensions so I know what parts to order online.
Build quality:
I was rather surprised that caliper felt rather heavy for its size, but then again, this is my first caliper so I had no idea how heavy or lightweight these tools are supposed to be.
All I can say about its build quality is that its made out of black ABS plastic(it has “ABS” written under its battery cover) and some heavy metal, nothing wobbles, nothing falls off, nothing squeaks or rattles and it measures accurately enough for my needs.
On the tail theres “Stainless hardened” in black print, Im not sure whether it means that it has hardened stainless steel body or its just printed there for the sake of giving impression on how sturdy its supposed to be:
Heres the short rundown on how to operate this caliper:
To turn the caliper on you have two options - you either simply move its ruler back or forth, it will turn on caliper automatically OR you can simply press the red OFF/ON button to turn it on.
To turn it off simply press the red ON/OFF button.
You can choose whether you wanto to measure in metric system(mm) or in imperial system’s units(inches). Changing modes is straightforward, when the caliper is on, simply press the blue “MM/INCH” button, press it again and youre gonna be back to the previous system, thats it, its that simple.
Metric:
Imperial:
When you want to measure something you will have to reset the caliper to zero mm/inches for accurate measurements, to do this, press yellow ZERO button, it will set calipers value to 0 mm/inches, since its rather precise instrument, youll have to do this every time you turn it on, otherwise it wont be as accurate as possible.
Even tho the error margin is really slim, somewhere around 0.0x mm/0.00x/0.000x inches, Id rather choose to have as accurate measurement as possible, thats why Im resetting it to 0 mm/inches each time I want to do some measurements.
All the measuring data, how accurate it is and how far will it measure as well as working conditions are shown in its manual:
This caliper runs from single SR44 button cell battery, as I already mentioned my caliper came with two batteries, one was installed in caliper and the other one came in original battery’s packaging.
Battery replacement is straightforward and requires no tools - remove the battery cover, replace the battery with a fresh one and slide the cover back on: 
One interesting thing about this caliper is that it has another, albeit smaller, cover on the top of it, there is no mention inside the manual what is this cover meant for, I have no idea either:
Couple of more shots of this tool:
Well, thats about it!
Overall impressions:
Rather cheap, well built, simple in operation, will be quite accurate as long as you dont use it for sub-atomic measurements :D!
I will use it for my flashlight related measurements for lenses, reflectors, drivers, tailcaps/switches, I think it will be good enough for these tasks.
Thanks for reading :D!
