10 Pcs Universal Microwave Oven Waveguide Covers, Cut-to-Size Mica Sheets

Used it. Worked as it should.

Small, inexpensive part that goes inside the microwave to prevent the arcing and vivid "lighting bolts" inside the microwave when the waveguide has baked on food or other damage. Impressive display of malfunction is easily and cheaply repaired. Don't replace the unit before trying this. The material supplies was larger than the origina but easily cut down to exact size. Measure twice, cust once.

Quality was a little better than expected. I could hold the sheet in my hand without fear that it would crumble. The only thing that went wrong for me was the inability to remove the little plastic pin which holds one side stationary, and two opposite corners are inserted into slots. SO, I had to cut a little bit of the sheet to make a slit to slide the slit sheet over the shaft of the plastic pin. (please don't kill me now, lol) I had read other reviews which said to use a brand new razor knife, etc. I used a nice pair of craft scissors. My only regret is that I was not careful enough in my measurements, and so I bent the corner of the sheet a bit much, and this weakened it at the bend. I was able to trim off the excess length of sheeting from my miscalculations, and everything fit very well after that. Highly recommend the product, great quality for the cost, I would buy this again if I ever needed to.

Worked well, easy to cut with CNC router. Shaper origin, to the rescue.

Worked great. Would recommend

I wasn't sure about this at all,but I was willing to try, to avoid replacing my microwave. It was super easy. I took the old waveguide out & traced around it on the new one. Cut it with scissors & put it in. I've had no more sparking. It's been several days. I got the universal piece so I didn't have to find the exact match. And I still have a spare if I need it. They could have been packaged more securely to prevent the thin cardboard from bending. Mine was not bent at all in a box with other items.

While the product met description, giving only 3 stars due to damage upon receipt. Made of mica, a fragile material, the cover was sent in an Amazon brown envelope without any rigidity resulting in damage to the product. LUCKILY, I was able to eek out enough to fashion the piece I needed. Other than that, product was easy to cut with a craft knife with a very sharp blade.

All of a sudden my microwave started casting lightning bolts. I thought for sure it was on its last legs and started researching buying a new microwave. Thankfully I came across some info that sometimes it's just this plate that needs to be replaced. My old plate simply came off with one screw. I used the old one as a template to make a new one from these plates using a semi-heavy duty scissor. I put the new plate on and the microwave is working perfectly again.
