Overview:
Hays Performance Drivetrain is proud to announce Twister 3/4 Race Performance Torque Converters. These NEW torque converters are a perfect addition to Hays product line of performance flexplates, clutches, and flywheels. The 3/4 Race torque converter is the first series being brought to market and is intended for street/strip combinations, with various RPM stall speed offerings to accommodate any mixture of modifications including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss.
The name 3/4 Race perfectly describes a torque converter suited for an application just shy of a Full Race version. We do plan to offer Full Race torque converters in the near future.
Good names never go away, and neither should good terms!
Hays Twister 3/4 Race Torque Converters!
Features:
- 3/4 Race series converters are built, tested, and proven to support up to 650 HP
- State of the art Spray Welding process is used in select areas. Spray Welding provides clean, strong and consistent fusion while also increasing strength through hardening from higher process temperature
- Each converter is hand-built and inspected in every step of assembly to ensure top of the line quality
- All HAYS converters are internally welded compared to brazing. Testing has shown welding provides longer converter life while also enhancing consistency
- Heavy duty Torrington bearings are used for greater strength and durability
- Stators are chosen with high flow vents and channels to promote cooling in heat producing higher horsepower applications
- Increased horsepower and acceleration due to a weight saving, one application design. Almost all HAYS converters are built for one application to reduce weight compared to a multi-bolt pattern converter.
- 3/4 Race series converters are offered in several different stall speeds for GM, Ford, and Chrysler transmissions
- Industry leading Tech Support Team is available to provide assistance with stall speed selection

Premium Print Quality Meets Economic Design
Color: White, Style: ET-2803, Pattern Name: Printer
I am very impressed with the manufacturer quality of this printer. It feels durable and well-engineered. The print quality is equally excellent; colors are vibrant and text is sharp, easily meeting the standards I need for both documents and photos.
Moving away from cartridges is a huge win. The ink lasts incredibly long, and the refill process is clean and simple.
The only thing I miss is a USB port for printing directly from external storage. My old HP printer had this feature, and it was extremely useful for printing files quickly without a computer. I wish this Epson model included that same convenience.
Final Verdict
A high-quality, reliable printer that produces great results. If you don't mind the lack of a direct USB drive slot, itβs an outstanding choice for home use.

Handles Photo-Quality Prints, Versatile Connectivity
Color: Black, Style: ET-2800-B, Pattern Name: Printer, Color: Black, Style: ET-2800-B, Pattern Name: Printer
I've had this printer for a whole year now. I was on a severe budget, looking for a photo-quality printer that didn't require Wifi in this digital age- because I quite frankly can't afford my own Wifi connection. My rink-a-dink laptop had to be set up with the software at my library, and an extra cord purchased.
All that said, I mostly print from my phone, because the software app is a bit easier to ensure that I get the highest quality setting. Laptop loves to be a snot about it. The blutooth feature, or "wifi direct", has a way about it, and as soon as you figure out what it wants, it gives minimal problems.
It functions exactly as if a printer had wifi on it, believe it or not.
What sold me on this model was the ability to do all of that, and adjust for different situations, seeing as other brands DEMAND constant wifi connectivity (lookin' at BROTHER, maybe Canon, too), and the long lasting ink tanks- I've printed hundreds of pages, and being a gothic/horror artist, at least a good part of the time, black is the only color even half gone.
What horrified me the most about printer-shoping dropping a lot of money (hundred plus is a lot over here, man) and not getting the prints to look like my work. Well, fear not. The attached pictures are why I made this review, to hopefully ease the anxiety of others. I make digital paintings, and use high DPI for high quality, and also the cutest micro-stickers you've ever seen. Prints come out clear, even if they can sit in the tip of my finger.
Yes, there are probably better printers. Maybe they're faster, and have even better connectivity, and have more bells and whistles. I specifically did not want to pay for those things, so, I'm very happy there's options.
It's not perfect, no, because every now and then, I get what I call a "special edition", where my printer has decided to multi-color barf out the last third of the page. One time it randomly printed in black and white. Well, that's no big deal, my stuff tends to look great in monochrome. Every now and then I get a low quality print; things just look a bit fuzzy. I'm not happy about that, but, you clean the heads, and print something simple and toony, and it has never done it twice in a row. Alignment has been off only one time, and I put the printer away after every session.
It occurs to me that people pay good amounts of money for printers that do that sort of thing anyway, so... Printers gonna printer, no matter where you try to hide.
Overall, I'm happy and relieved. I hope it lasts me a good long time. (Streetratt on Kofi, by the way.π€ )

Great functional printer
Color: Black, Style: ET-2800-B, Pattern Name: Printer
This is a great basic printer for my office. We have a higher model in our main floor office but it is older. The setup is fast and easy and it prints well. I set it up right from my phone. The picture quality is great and it prints quickly. It is so convenient and was the right price for what I need.

So far so good.
Color: Space Gray, Memory Storage Capacity: 32 GB, Size: Wi-Fi, Color: Space Gray, Memory Storage Capacity: 32 GB, Size: Wi-Fi
Seems to be working perfectly. Battery is a little meh, small scratches but nothing that effected the screen.It'll be perfect for my child. It'd be in excellent condition if the battery were better. Worth the 100 bucks.
