Notice of Price Revision

Due to the significant increase in raw material costs, driven in part by rising crude oil prices, it has become increasingly difficult for us to maintain our current pricing for components and other materials.

After careful consideration, we regret to inform you that we will be increasing the prices of all ARS products, effective September 1.

We sincerely apologize for any inconvenience this may cause and greatly appreciate your kind understanding and continued support.
