Review on 🔧 Befenybay Professional FlexRem 250x250mm by James Wiley

Diameter 240 mm. 08/10/2020 Upgrade and downgrade to 1 star: Very short lifespan. days from installation at the end of June. I loved using both PETG and PLA. I was even able to lower the bed temperature to 55°C and 45°C respectively. Parts have always come loose easily, hot or cold. With PLA and a working temperature of 45°C, I was comfortable removing the magnetic surface once the print was finished and just peeling the print away. Today I turned it on and went to lunch. I went back to the straight old filament rat's nest dangling from the hot end. I paused, cleaned the surface, wiped it with alcohol, and started typing again. This time about 40% of the first layer sticks. I stopped and gave the bed another light scrub with 3M Scotchbrite and an alcohol wipe. Grip got a little better, but still only about 50% chose to stick with the program. As you can see from the 2019 questions above, not only does this vendor offer the top magnetic layer and $14 for a full replacement, half of which I don't need is too rich for me. As handy as it is, I can't justify paying $14 for a full set every 5 or 6 weeks, so go back to the spatula for me and toss the whole thing in the trash. 06/26/2020 Original 4-star review: I just recently installed it and made about 20 medium sized prints in PLA (210°C + 50°C) and PETG (250°C + 60°C) and it works fine. Both materials adhere well to it and come off easily when it cools down. The magnetic grip with the included 3M adhesive base seems to be good and haven't had any issues so far and I print pretty much everything at 100mm/s. In general I am very satisfied. I just finished a 2 hour PETG print (250°C + 60°C) of 3-1/2 inch tubing and noticed bubbles under the release liner. I don't use extreme temperatures, 250C for filament and 60C for bed, so I think they should be comfortable with that. I'm done. I will try to poke the bubbles with a needle and push them down as they will form a slight bulge at the top when the release liner is in place for printing. head turning or not.
