I have ordered several items from Telonic UK - Scope, Bench DMM, VNA, Power Supplies, differential probe + other bits and bobs.
I recommend them with no hesitation whatsoever. Excellent service.
You find out about service when something doesn't go right and I did have an issue. Between Siglent HQ and Telonic the solution was seamless - no fuss at all. I also returned a Siglent item that I thought wasn't right. They checked it out and were obviously, if very politely not 100% convinced about my diagnosis (if it was for a work test bench then I would have accepted it but even the smallest of cosmetic things bothers me for a big investment at home). But regardless, they offered a new replacement if I wanted it - and I did.
You have admin support from someone you can speak to, not a faceless customer service rep in some distant land. This came in handy when the courier delivered my parcel to a wrong address. Not Teloic's fault. Also technical backup second to none.
My advice - don't use Amazon, use Telonic.
