Great for us older folks

Ok, I admit it, sometimes these old eyes aren't so great at reading a tape measure. My reading glasses only focus out to about 2' and my stiff neck and back sometimes (always) make hard to get my eyes where they need to be.

Enter the T1. Inside measurement, check. Outside measurement, check. Nice big display with the accurate measurement, check. Now, I'm not using this on a construction site, so I can't talk to that aspect, but for my needs it's been great. I do use it many times a week, though, and it's stood up to my clumsiness fine. I've dropped it multiple times onto my cement shop floor and there is no evidence it's been dropped.

$260 is a lot for a fancy tape, and I don't know if I'd pay that, but I got mine as part of the Kickstarter program for quite a bit less.


UPDATE...6/30/24...RMA-ING TAPE MEASURE This week....hopefully its just 1 bad device

For a $260 tape measure...
-it needs an update to turn off the Paper Screen as well so it can actually Turn off...

-The Replaceable Blade sometimes sticks so i have to pull the whole thing out and Re-Wind it back up.......

-The magnet can hold up to 15Ft before it loses its strength and pulls off

-The Replaceable blade is quite Flimsy cause after i bent it for 3 seconds i can still feel the bend in certain places so its best not to bend the blade and use it carefully

-Smartphone app is Usefull only if your getting millions of people to buy it $260 a piece... you can afford the free app with updates....(maybe if you work at construction then yes a premium app is good but not like a warehouse job)
-all in all this is a 3 star to 4 star product....5 stars if they fix everything above first


Great Tool To Have Makes The Job Easier, Run Smoother And With More Efficiency.
