AMAZON REMOVE THEM FROM APPROVED REMANUFACTURER LIST...First the unit itself. It's perfect for everyday computing web browsing and video streaming like Plex or Jellyfin. Super small form factor, quiet, and decent multitasker.MY problem is with "GIZMO BING" seller. The attached photos are what I found right when I opened the case to see how well they went through the unit when they remanufactured it. Besides a new "Tech Magnet" (Ultra cheap ssd) drive with a sticker stating it has windows 10 on it there was nothing touched. The dust and dinge buildup looked like a unit that hadn't been dusted in years AND WHATS WITH THE BUG!!! There was also evidence of some fluid inside the case with water spots on the back edge by the CPU exhaust port.Here was my list of issues as I started to test the unit and my fixes. I'll follow up with my response I received from GIZMO BING! NEVER BUY FROM THEM1.) Thermal Throttle on load (Bad CPU/cooler thermal paste)- I attempted to run a few stress tests to see how it handled a load and also thermals.  I was sidetracked by slow boot-up, system hangs on boot, random freezes and crashes. (all after system hardware and software updated from HP) This ended up being a memory problem so I had to buy RAM. Once I was stable and able to run some stress tests I could barely go 5 minutes till it would start to thermal throttle the CPU. This is only a 35w cpu with an active cooler...this should not be an issue. The cooler and fan were dusty and had a few minor blockages I blew out when I cleaned the unit. I decided to check the cpu and cooler contact and thermal paste. When I checked it was like chalk, it was dried and cracked. I had to get some thermal paste reapply the air cooler. Once that was changed I could run the system under 100% load for hours and still have 25 to 28 deg C distance to thermal throttle for the CPU.2.) System hang, boot erratic and memory test failure (new DDR4 ram sticks)- See above " I was sidetracked by slow boot-up, system hangs on boot, random freezes and crashes. (all after system hardware and software updated from HP) This ended up being a memory problem so I had to buy RAM." After these issue I found the problem running memtest to see if there was a failure with the ram and there was. When I replaced it it ran fine and smooth.3.) System has a M.2 ssd slot- Unusable due to dirty contacts, I cleaned them and I was able to get it to read correctly and install the OS onto it because I didn't trust the cheap bulk 2.5in SSD. Unit was dirty in general, I had to blow it out and remove dust from fan and CPU cooler along with cleaning off some sticky dried on fluid from cooler as well as from motherboard. I'm just glad nothing shorted out.So after a few days and half the cost of the unit later (not counting my time) I was left with a great unit.When I reached out to the company on a weekend I was told I would receive a call back during the week about a partial refund. I felt that was fair due to having to spend about $100 dollars or more to get it working properly and "remanufacture" it myself because besides a new SSD the unit wasn't even touched.I hope AMAZON reads this and removes GIZMO BING from their approved remanufacturer list and makes them list this unit as "USED."  I was happy to pay more for a unit I didn't have to rework myself to get working properly, I was upset I spent over $200 on a unit I could have gotten used for cheaper and fixed myself.Overall, I'm very disappointed with this purchase and seller. If I didn't have the tech knowledge and experience I have I would have probably been a more upset customer and returned the unit.I have attempted twice now to talk about a partial refund due to time and money I spent to repair the unit and both times I was told I had to call back Monday or a week day because no manager was avalible to help me.
