Great value and precise cuts!
I purchased this with low expectations but man was I surprised. This thing works great and is very precise. The unit is easy to operate and comes with a well written manual. It also comes with a pack of biscuits of various sizes to get you started. The hard plastic case stores the unit nicely. I recommend this product for DIY's and professionals alike.

Great, but do replace the blade that comes with it
Overall, for the price this is a great tool. I did end up replacing the blade that came with it with the CMT 8-tooth blade mentioned in some of the other reviews and it fixed the issues I was having which were: biscuit fit, burning smell after a cut, and the ease of pushing the tool when cutting. The dust collection, as mentioned in some other reviews, is not that effective so I ended up leaving off the included dust bag to avoid clogging and then just dealt with the mess that I made. Despite this items, for a hobby, value-minded builder this was a good buy. Even with the replacement blade it cost well less than a big-name brand joiner

Excellent biscuit joiner
This biscuit joiner works amazing for the work I do. I tested with 100+ biscuits in solid alder using the factory blade and it worked great! The alignment is perfect and nice and tight. I really was amazed at the quality for the price. WEN tools have always been great for me

Awesome and very handy tool to have around the house or shop
I needed this for a special project, and not ever having used one before, I was extremely impressed with 1) how incredibly easy this tool was to use 2) how well it works and 3) how incredibly strong the joints it produces are. That said, I wish I had bought one of these years ago!!!

Works as it should. Cannot ask for anything more.
Works well. Does what it is meant to do. For as little as I will be using it, this is perfect. I may only use it a few times a year. If I was going to use it weekly or daily I would have gone with a more expensive commercial quality tool. Why spend hundreds for once or twice a year. All my mechanic tools are all pro quality. I have always believed if you buy quality you buy once. You buy cheap “ Homeowners “ grade tools you will buy again and again. With this tool and what will be my use, this will be fine.

Great tool for the price
Just received this the other day, and had my first opportunity to use it yesterday. Setup is very easy (except for the depth adjustment) and works very well overall. The only real flaw in its operation is the dust collector. This chute is very narrow, and clogged almost immediately. The collection bag provided barely had any sawdust, as it couldn't get through the chute. I would have to vacuum it out after every few cuts. The other negative of this tool - and the reason for 4 stars - is the depth adjustment. The lock-nut is an odd size - I think 7mm though I haven't found a wrench that fits yet, and it comes with so much thread lock on the tiny screw that it is really hard to turn (I had to adjust mine for the harbor freight biscuits I bought because their #0 were just slightly larger than the one that came with the cutter. Overall, I do recommend this tool for the price. I can't imagine the need to spend hundreds of dollars for something where the $50+ I paid does the job. I only wish I had owned one of these tools years ago!

Buena calidad y bien precio
Se siente bien la he ocupado poco pero, creo que rendirá, tenía una Dewalt pero me la robaron y no quise volver a gastar porque es una herramienta que ocupo poco pero se siente bien las pocas veces que la he utilizado, la recomiendo por el precio y la manufactura

Great tool
I'm a Milwaukee guy, but I love WEN. Bought this for a project my wife wanted. Now I'm looking for projects. I've got a WEN jigsaw and planer and love the quality. On the rare occasions that I loan out a tool, WEN always gets accolades. Solid build. Great performance.

Custo benefício
Excelente custo benefício. Para hobista está ótimo.

The information let it down.
Could have been great, will never know, because this is a US only plug and doesn’t (at least at the time I returned it) state anywhere of that. I did check at the time and was told it’s a uk plug. Couldn’t even safely change the plug as this is a single voltage item (110 and not 230v)

Not bad
Not bad... All the 8.5Amps joiners from China are basically the same except for the color and some minor differences, this one has a case and some biscuits so it's the best deal. I only used it once so this is a basic review. I like the trigger with the safety, simple to operate and much better compared to the old on/off grinder switch. the adjustment for the height is not as obvious as the other options, there is a hidden arrow on the side. I tested it on 5/8" Baltic Birch (15mm) the blade slightly burned as you can see, the motor struggled just a little bit. I've noticed on other cheap joiners that the problem (precision) is the plunging mechanism, this one has a little less play in it but it still has some play as you can see in the video and in the 2 pictures with the pencil mark, one has a 1/32" difference which is not that bad, the other 4 biscuits were ok. I will be using this joiner on an upcoming project so I will update this review if I have anything else to add.
