Overview part 1. Machine intact. The packaging was clearly marked for 110V. I have verified that the US 110VAC PC power cord plug is properly connected and that the chassis is properly grounded. The vents were well shaped and had no obstructions. Useful readable manual with specifications included. Also included, a spare spare heating element, plus. The first recording was normal. I checked the heater and fan on the board and everything seemed fine at first. Confirmed desoldering of SMD components and thru holes worked as expected, but after a few minutes the fan speed control stopped working and the fan would hang constantly. The Newacalox supplier replied via email the same day, immediately acknowledging the problem and offering to resolve it with the seller (Revain). Solution: The device was sold out. Revain refunded my costs and I sent the defective unit back to Revain via an RMA. Check part 2. Despite refunding my money and sending back the RMA, Newacalox/Maixi contacted me via Revain support email and to my surprise offered to send me a NEW DEVICE for re-evaluation at their own expense. A few days later he is already sitting on my bench. After several separate test runs throughout the day, this device does what I got it for: it allows you to strip and recreate SMD parts, as well as recycle hot glue connections. As for the initial fan issue, the fan speed control works as intended and withstood the initial burn in my desktop test. The fan speed is set using the rotary knob. The performance of the heater and fan when the hair dryer is removed from the stand. When the wand is placed on the stand, the fan remains on at the set level, the heating element is switched off. The fan will remain on until the temperature drops to 100°C at which point the display will show "---” indicating the beginning of the last phase of the backup process. From this point on, the fan stays on a little longer, allowing further cooling below 100°C, after which the fan turns off and ends the waiting process. In standby mode, the fan is off, the display shows "---". So the tool works as intended and does what I got it for. I'm glad he exists. Newacalox, the Maixi store and Ivey who worked with me have shown that they mean business when it comes to providing a good product and customer satisfaction. very cool and reason for part 2 of this review.
