It was delivered next day
Size: 8 Line Spools+2 Caps
If it's like the previous line I purchased, it's good. Don't leave it in a hot garage, because the line will sometimes stick together when you get around to using it! NOTE: Again, I received this product YESTERDAY, and Amazon is sending me a survey today!! What AMAZON brain surgeon thinks that this is a good idea????

A portable power house built like a tank.
Style: Apple M5 Pro chip, Capacity: 24GB Unified Memory | 1TB SSD Storage, Color: Space Black, Set: Without AppleCare+
A well built powerful portable laptop computer with brilliant colors and a stunning 16 inch high definition screen. Consider your working space size as it is large and heavy: this portable is built to last with heavy use. Note, track pad is large, hands may cover right and left sides of touch pad while typing. There is not a part of this powerful device where production cost short-cuts were made sacrificing quality. The premium price for this Apple product is money well spent for dependable reliable blazing fast performance. Purchase this portable power house with confidence as it runs on the Apple operating system which is the envy of every global lap top competitor.

Great MacBook
Style: Apple M5 Pro chip, Capacity: 48GB Unified Memory | 1TB SSD Storage, Color: Space Black, Set: Without AppleCare+
The computer feels fast and smoothly, the screen quality is great, for me 1TB is more than enough. Not that suitable for portability purposes cause it is quite heavy.

Mac Pro = Worth It!
Style: Apple M5 Pro chip, Capacity: 24GB Unified Memory | 1TB SSD Storage, Color: Space Black, Set: Without AppleCare+
This Mac Pro completely changed the game for me. Absolute powerhouse. 🚀 No lag. No crashes. Just nonstop performance no matter how hard I push it — especially with AI workflows and multitasking. I put this machine through heavy work every single day, and it handles everything effortlessly like it was built for the future. Officially done with PCs. Apple really operates on another level. 🍎🔥 One VERY satisfied customer.
