External – Nice box with carry handle; attractive with good graphics; shows contents and details; sturdy for long term storage if needed, has tab-locking lid for good closure
Internal – Opens easily with use of sharp knife; product parts fit easily inside and are easily removed; small item in separate zip bag right on top in plain view when box first opened
Attractive color scheme, very comfortable for my height (5' 11”) but may be nice to extend handle for taller people (over 6' 4” or so), uses 9volt battery type but might be better to use AA or AAA rechargeables, heavy-duty construction of all parts, easy battery installation, wrist strap does not appear to be mentioned in documentation, display appears to stay on even if turned off, bag appears adequate for storage and carry of folded unit, easy to attach pointer and install battery
Unit turns on by pressing red "On/Clear" button. There is no Off button. However, unit is turned off by holding red button for one second. It claims an auto shutoff after 8-9 minutes of inactivity which I was able to verify.
The DigiRoller rolls easily and feels positive in the hand. I liked that it seems to hold contact with the ground even when bumpy. It appears to have a good weight for that purpose, so the design of the DigiRoller is also good in that regard.
The hand grip is comfortable enough and likely not to cause fatigue during long use periods. Smaller hands may find it a little large, but still usable.
The hand-strap apparently loops onto the hook opening at the rear of the handle, and although the strap line is very thin, it did work to keep the wheel from falling out of reach and did not break. It appears stronger than it looks, even though almost exactly like the one you would use on your smartphone.
The digital readout is good, with buttons easily activated and with positive feel and action. It includes the standard distance measurements in meters, decimal feet, yards, feet & inches, or inches, and it will automatically round off to appropriate measurement units if it exceeds the display length. But this unit will also do area and volume calculations as well.
The display has a back-light feature to make it easier to view, but can be turned off manually to save the battery. I also like that one can take interior measurements by rolling up to a wall and pressing the “+ ½ wheel” button to add the wheel's radius to the measurement.
The instructions clearly indicate, by simple steps, how to use the accumulative memory feature along with all the calculations it will perform for the user.
Safety is supported well by having the yellow/green safety color and a reflector patch on the upper handle shaft.
I found one problem with the device, and that had to do with the pointer. It is attached below the protruding drive mechanism on the right side. Neither left- or right-handed operators could see it while standing upright, but had to bend to the left to see where it was pointing. But this small problem is not a deal-breaker.
Folding it and putting it in the carry case was fairly easy, but would have been more easily facilitated by a case that was an inch taller. However, for hiking into a remote area, it does work well as a backpack-style carrier, and would be extremely convenient for that purpose.
This tool is a commercial-grade device, and includes professional features. The DigiRoller is well made with a two-year warranty, and I would consider it a welcome addition to a tools-set in whatever occupation required accurate longer distance measurements. I consider it a Good Buy.
