Thank you for all your help.

I will be buying another 100 pieces.

Please send me the bill.

There was one piece which was defective (the sensor was defective).
I hope you can deduct $41 for the cost of that item from this order.

I intend to send the defective items to you once I have accumulated a few.
I hope they will be of use in improving the product.

I will be sending the payment through bank transfer as I did for the previous transaction.

Looking forward to your favorable reply.

Thank you.

Translation / English

Thank you for your continuous support.

We will place an order for another 100 of them.

Please send me the bill.

Unfortunately, one of the product was found to be inferior (inactive sensor).
I would like to ask for 41 dollars (cost of the inferior good) subtracted from the total this time.

I would like to send you back the inferior goods when they accumulate in future.
I would be happy if you could use them to improve the product quality.

The payment will be made through bank transfer as last time.

I am looking foward to your kind response.

Thank you.
