This company produces products that offer a good value for the money. Generally, if you operate the products within the conditions outlined in the manual, they work reliably. Unfortunately, the manuals are often full of errors and incomplete. However, not all of their products work properly. Sometimes it's a hardware failure, other times it's a software failure. And they are constantly revising the product line, making what you bought 6 months ago completely obsolete and unsupportable. Then there's the matter of customer support. In my last attempt at resolving a technical issue, it required nearly 4 months to get past "Do you have the power switch turned on?", followed by "Are there any cables connected to the unit?", which is often followed up by "Send a photo of it", followed by "Disconnect all cables and turn the power on", which, after disconnecting the unit, there is no longer a power source, so after explaining that, they ask "Please send a photo of the display" (which of course is blank), and after you do that, they conclude that you need to attach cables and turn the power switch on. Problem solved. Lather, rinse, repeat.After about 8 months of constant back and forth, they finally admitted that the firmware in that particular manufacturing run of this particular model was defective. So they sent me software to upgrade it, but the software was defective, so it was not possible. As it was under warranty, I asked to replace the units, but they are no longer made. So I asked about the newer version, and they offered me a slightly discounted price. I ordered it. But it turns out to be completely incompatible with my existing (defective) equipment, so now I have no choice but to replace all of it.
