I just recently placed an order with Tenda during CNY, after I budgeted and email transferred >400$ for some decently priced stuff I've been eyeing for way too long. Unfortunately, there was a bit of a miscommunication and they didn't actually have in stock the quantity that I ordered. NO JOKE, 10PM on the day I placed the order, I received a sincere apology with an explanation as to where communications broke down and received a full refund next business day. Overall, I'm very impressed with the service I received and I will continue buying from Tenda without hesitation. They don't take advantage of your payment method, atleast in my experience. They handle themselves better than Marstar but I haven't dealt with Marstar in years after their BS. YMMV
