I didn't use these wire cubes for their primary purpose. I did in fact use them to make 2 guinea pig C&C cages. The grids and connectors are well made, strong and sturdy when put together and I received all pieces that the description said I would. Very good value for money - one of the cheapest I found. Very impressed with Wayfair, They kept me up to date about delivery even down to the time frame on the day I should expect to receive the product. I was a little hesitant to use Wayfair as I'd never heard of them before. I can honestly say after the smooth transaction and helpful customer service I received, I'll definitely be using this site again. Fast and reliable. Really pleased with everything! Thanks Wayfair!
