Is M3 the right product for me?

M3 works flawless and most effective across Asian sub-continent. However, we strongly encourage you to cross check the list of birds and animals that troubles your airport against the list of 67 species of birds and 7 species of animals on Harmony.

  • Damages to the equipment would be assessed before replacement. Intentional damages are not covered under warranty, if you open the M3 unit your warranty expires immediately. In such case you are entitled to pay full amount towards the equipment loss. Also, you can not physically re-locate M3 on your own without consenting with Grus Ecosciences, such act immediately disqualifies you from all sorts of warranty.
  • If we are unable to replace the equipment immediately for any act of god or force majeure we will credit those non working days of M3 to your account and extend the rental time FREE of cost. For example, you raise the ticket on 1st of the month and replacement is given to you on 20th, then your account will be credited with 20 days of extended time, free of cost.
  • The reduced TCO calculation is done keeping a customer moving to EMI scheme after six months of rental period. This can vary dramatically depending on when you move from rental scheme to EMI scheme. We don't guarantee 19% savings in any other transition mode.
  • If you are breaking the initial six months contract, then you will have to bear the un-installation expenses which generally involves two way travel for our engineer and any damages to the equipment.
  • We do the installation free of cost during the time of rental scheme start, any shifting later, attracts TA and DA for the engineer visiting your premises. The cost of TA and DA are governed by Grus Ecosciences and you can not influence the cost structure. Shifting the equipment without Grus Ecosciences's consent would void all the warranty on the equipment and Grus Ecosciences reserves the right to pick the equipment before the tenure time.
  • Any issues with the equipment must only be attended by Grus Ecosciences engineer. In case if any tampering is observed on the equipment, not only would you lose the warranty but also Grus Ecosciences reserves the right to pick the equipment before the tenure time. Any tampering of the equipment attracts full recovery of the total equipment cost.
