The Company generally warrants its products against certain manufacturing and other defects in material and workmanship. These product warranties are provided for specific periods of time and are applicable assuming the product has

not

been subjected to misuse, improper installation, negligent handling or shipping damage. As of

and

2016,

the Company’s accrual for estimated product warranty claims totaled

$180,000

respectively, and is included in accounts payable and accrued expenses. Warranty claims expense includes the costs to investigate claims and potential claims, and the costs to replace and/or repair product pursuant to claims, which can include claims

not
