Unprefessional company I placed an order for a Display Link adapter. Their website said it will reach me within 5 days in Germany. After 5 days, I emailed their customer support. Never got any reply. The next day, the order was cancelled without any explanation or reply and I got my refund. Meanwhile, I wasted 5 days then had to order again from Amazon. I think their customer support doesn't exist or they don't know how to handle customers in a professional way. A reply would be a "normal" response when your customer reach out to you about an order.

Qgeem Thunderbolt 4 Mini Dock A Bust Based on both company claims --"Leading the Times Technology: QGeeM Thunderbolt 4 Docking Station is committed to providing unparalleled simplicity, the highest performance and the most reliable connectivity" -- as well as Amazon rating of 4.5 stars, I purchased the Qgeem Thunderbolt 4 Mini Docking Station on January 27, 2023 from Amazon, where Qgeem additionally boasted "18-month warranty, and friendly customer service". Turns our they have none of the above. Within 10 months the product failed. After some circuitous emailing, Qgeem did some walking back on their support boasts: "Our products provide 3 months free return, 6 months free maintenance and 18 months free consultation service. Since your purchase is beyond the 3-month free returns period or more, I can no longer arrange a refund or exchange for you. If you return the product to our warehouse for repair, it will cost you high shipping costs and a lot of time. Our suggestion is: refund 30% of your order amount as a repair fee, what do you think?" Well, I thought I'd take that offer, but as it turns out, that was also exaggerated.... and evaporated almost as quickly as it had appeared. Subsequent emails to support01 at qgeem.com were never answered. So, buyer beware of Qgeem substandard items offered as premium, at premium prices with lofty claims. Oh yeah, Amazon couldn't care less.... Good luck, mates!

Bad service and products Bad service and products, broken in 2 days

Slow shipment and no communication other than review. Hub appears good quality. Took much longer to receive than expected, about 12 days, no communication when it shipped as indicated on purchase confirmation and no response to my inquiries about shipment. Other than that it appears the hub is a quality device.

Support is very slow Support is very slow. I sent an email inquiry and received reply only 4 days later informing me the item was out of stock. Then I requested refund. Again no reply for 5 days until I further followed up. Otherwise, the refund is smooth.
