Customer Reviews
CNC Router experience
I bought a Genmitsu CNC Router. The machine itself is quite capable for the price point, and it arrived well-packaged. Setup took a bit longer than I expected from the instructions, but I got it running eventually. Customer service was responsive when I had a question about software compatibility. Shipping was reasonable, took 5 days to reach Denver. Overall, a good purchase, but the setup guide could be clearer for new users.
Good laser engraver
Got the Laser Engraver. Shipped fast. Works as described. Setup was easy enough. Happy with my purchase.
Consistent quality for bits
I've ordered from SainSmart a few times now, mostly for CNC Router Bits. This last order was for some End Mills, and they were just as good as the ones I got before. Always reliable, the quality is consistent which is why I keep coming back. Shipping is usually pretty quick too, no issues there. It's nice to have a go-to place for these parts.
Great value on filament
This was my first time buying from SainSmart. I needed some PETG Filament for a new project. The price was really good compared to other sites, especially with a first-time buyer discount I found. Got a bulk pack and it felt like a solid deal. Definitely worth what I paid.
Easy to order, quick delivery
Needed some Jumper Wires and an Arduino Starter Kit for a project with my kid. Found SainSmart online, the site was easy to navigate. Placed the order, didn't have any problems. It got here pretty quick, like in four days. Everything was in the box and worked perfectly. Pretty smooth experience all around, would totally use them again.
Detailed review of 3D Printer
I purchased an FDM 3D Printer from SainSmart a few weeks ago. The ordering process was straightforward on their website. It arrived within a week, which was decent. Unboxing and initial assembly were manageable, though the instructions could benefit from more detailed pictures or a video link. I also bought some PLA Filament with it. The print quality has been surprisingly good for the price, after some minor calibration. I did have a small issue with the heated bed not reaching temperature initially, but after checking connections and a quick firmware update, it resolved itself. Their support documentation online helped with that. I also picked up a 3D Printer Leveling Sensor later and it integrated fine. For anyone looking for an entry-level FDM printer, this one performs well once you get past the initial setup quirks.

Hey, I'm looking at getting one of the Genmitsu CNCs. How long does shipping usually take to like, California? Trying to plan out a project.
Can you stack discount codes on SainSmart? I've got one for signing up for the newsletter and then saw a Black Friday one pop up.
