Khiyaarur ruyat (the option of buying or returning an item) for defective items on online purchases

Q: I humbly request your guidance and a detailed, evidence-based response regarding the following scenario: 

Our business sells pharmaceutical machines and occasionally encounters defective units. When a unit is defective, we explicitly inform potential buyers of the defect, share photos of it, and sell the machine at a discounted price. Despite being made aware of the defect, some clients later refuse to pay, citing the defect as the cause. Additionally, we sell various other electronic items through our online store. 

In light of this, we request clarification on the following points: 

1. Seller’s Obligation to Accept Returns: If the buyer refuses to pay or wants to return the machine on the basis of a disclosed defect, is the seller Islamically obliged to accept the return and refund the buyer? 

2. Application of Khiyar-ur-Ruyah: Does khiyar-ur-ruyah (the option to inspect goods before finalizing a sale) apply to pharmaceutical machines sold with clearly disclosed defects? 

3. Khiyar-ur-Ruyah in Online Sales: Does khiyar-ur-ruyah generally extend to products purchased online, where the buyer may only see images rather than physically inspecting the item prior to purchase? 

Earnings of a person selling Christmas trees and related products

Q: My brother sells Christmas trees, Christmas related products on which happy Christmas is written and he paid my education fee. 

Will my income be halaal if i use the knowledge as a job or business that I get from my education and can I live in his house that he made from this money? 

Also, he gave me a laptop that he bought from that money and I work on the laptop as a freelancer. I use the Internet on this laptop and he also pays the bill of this Internet from that money. Will my income be halaal that I make from that money?

Informing the customer about a defect in the product

Q: I sell 1m lengths of pipe at R80. I purchase these ready cut. I have a marking on my counter to measure 1m. Those who purchase don't specifically require 1m but purchase the metre as that's how it's sold. It is advertised as 1m. I noticed a pipe today that was marginally short. I therefore refunded R2 to the customer but did not inform him why. The pipe will still fulfill the function for which it was purchased. What is the ruling regarding this transaction?
