"I have a number of things purchased from here, from Arduinos, Raspi's to 3D parts and filament.
They always deliver, and their shipping is faster than AliExpress for example.
Prices are decent, and they are quick to respond when I had to cancel an order for example."

"I am satisfied with the order as delivered."

"great quality and service"

"So rare is there a problem with something you get from Sainsmart. This ONE time there were a problem with a new item. (Not their fault) But, Sainsmart customer service was right there answering my concern. Like magic I received a replacement item only a few day's later ! Wow, no questions asked and no hassle at all. Besides that, I received two follow up messages to track the progress of the replacement. The replacement works perfect and as expected. You just can't get better than this. Thanks Sainsmart for your great attention to us small people. You are on my A+ list.

"Very happy with my Sainsmart Filament Dryer V2 and with their prompt service. I use this for PLA, PETG, TPU and ABS. I usually just put a spool in the dryer for a couple of hours (depending on the filament) before I put the spool on the printer. My son also bought the Sainsmart dryer and prints straight from the spool while it's in the dryer. If you are experiencing pitting or stringing in your prints, this probably is a solution for you. In contrast to a oven or food dehydrator, the Sainsmart dryer does not heat the whole room. Yes there is some heat, but I don't feel like it is blowing up my electric bill just to cool the house in the Texas summer.

I'm not affiliated in any way with Sainsmart and I'm not providing this review in exchange for any benefit. "

"The machine is robust and easy to assemble. It needs an instruction book on how to load projects into the machine. I have to watch a you tube video to figure this out. Will be happier when can use it for real."

"The unit does exactly what we need it to do. Very simple to use. I was most impressed with the delivery speed. Fantastic."

"Shipping time could be improved, but I didn’t get any problem buying here. I choosed the item, told where I want to receive the product and how I want to pay ... then I waited some weeks and got what I bought. After about a month, the item stopped working, and customer service replaced it in a few days. Very good job: thanks a lot.
The item was exactly as expected.
I’m sure I’ll buy again in this shop"

"Got exactly the items I ordered, very fast as well, only issue was the packing wasnt the best, some of my package was kind of damaged from lack of proper padding "

"Bought a 5,5w laser for my CNC3018 and contacted the support, asking if they could ship from EU, and less than 8 hours later they had fixed it and i got the laser fast and whitout trouble with customs and post..

They are great "

"Fast shipping as always from these folks"

"I had a faulty lamp and the support team got back to me and sent out a replacement quickly. No complaints here!"

"I ordered the wrong item & the return, reorder and item delivery time took too long. It was a gift 4 my wife's B-day hich I missed by a week. "

"I purchased:
Genmitsu CNC Router 3018 DIY Kit
Genmitsu CNC Router Bits Essential Kit with Collet collection

Assembly: Took a few hours, but not very difficult to understand if you look at the pictures on the website as well as the assembly book.

Getting started with milling: This will probably be the area where you start to get a little frustrated but also excited as you learn more what all it can do.
I used Candle for grbl control, and started out using the gcode tools included in inkscape for the design software. It took awhile to figure out how to use it and get what I wanted from it, but eventually it came along somewhat nice. After I got tired of not being able to do very nice 3D textures/designs....so I switched to Autodesk Inventor+Inventor CAM (Free with an educational email address)

The Router itself is absolutely *flawless* if you program everything right in the 3D designs. Very very accurate and detailed. :)

Overall, I am in love with this machine and the customer service given by SainSmart about any inquiries I had. Very quick to respond to emails and attempt to remedy any problems.
The only suggestion that I would make is buy some Red Loctite Threadlocker and put it on the set screw for the stepper motor coupler. Other than that I would just say have fun!

"It was great, they told me after I had ordered that they were currently out of stock but would tell me when it was shipped. A few days later I was told the parcel was on its way and a few days after that I was ready for my first run!"
