Customer Reviews
My first laser engraver!
So I finally caved and bought a Laser Engraver during their holiday sale, and it just got here. Setting it up was actually easier than I thought it would be, which was a relief. I've only done a few test runs on some scrap wood, but the results look really clean. I was a bit worried about getting started with something like this, but the online guides were pretty helpful. Shipping took about 5 days to reach Denver, which was totally fine. Definitely excited to try some bigger projects this weekend.
Good router, slow support
I bought a Genmitsu CNC Router a few weeks ago and it's been working pretty well for my projects. The build quality feels solid, especially for the price point. Assembly took a bit longer than I expected from the instructions, but I got it done. My only real gripe was when I had a question about the software settings; customer service took about three days to get back to me, which felt a little slow. Overall, a decent value if you're patient.
Filament arrived fast
Ordered PLA Filament. It shipped quickly. Quality seems good. No issues printing with it yet. Happy with the purchase.
Consistent quality, as usual
This isn't my first order from SainSmart. I needed some more End Mills for my CNC router and decided to order from them again. The quality was consistent with what I've received before. They always pack items well, and shipping is reliable, usually getting to me within a week. I keep coming back because their parts are dependable for my projects. No complaints this time either.
Decent deal for a beginner
I was looking to get into 3D printing without spending a fortune, and found a good deal on an FDM 3D Printer here. It wasn't the cheapest option out there, but with the bundle offer they had, it felt like I was getting a lot for my money. I also grabbed some PETG Filament since it was discounted with the printer. So far, the prints have been consistent, which is great for a beginner like me. I'm definitely satisfied with the overall value I got.

How long does shipping usually take from SainSmart? I'm in California and want to get a project going soon.
Can I use a student discount AND a newsletter signup code on the same order? Trying to save as much as possible on a new 3D printer.
Hey, thinking about grabbing one of their Genmitsu CNCs. Do they ever have any decent sales on those, or should I just bite the bullet now?
Is SainSmart legit? Never heard of them before but their Genmitsu CNC looks like a good starter machine compared to something like a Shapeoko.
Thinking of getting one of their laser engravers, but kinda worried about returns if it's not what I expect. How's their return policy for the bigger items like that?
