Title: old and unreliable
Review: I purchased this palm calc to speak to HVAC equipment, (Siemens software)still runs on DAS. Unfortunately the display screen only worked for 1 day of use, which is unfortunate enough, At which point I contacted the seller for return , which was granted, I lost about 21 hours of man time due to this which ads up to approximately 2600 dollars, And the seller now is trying to deny me my refund of the item After I sent it back! I dont think I will ever except another contract were Iam responsible for communications to do my job since most HVAC software is out dated and old electronics are unreliable the seller of this product is a con artist selling broken crap online than making false claims I hope Amazon sticks by there Gaurantee!
