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

WEN tools have gotten better over the years.
If this was a DeWalt or a Bosch I would give it a 4 star review. But at this price point, it works fine. Typical brush smell on first startup. Calmed down after a bit. Plenty of power. Seems fine for the little bit that I need this.

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

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!!!

Great working Plate and biscuit joiner. I'm sold on WEN...
This is one of the best WEN products I've ever used. I used to swear by my rhobi, but this WEN is the hands down winner.

Alas, for wood not baking.
Excellent. Elevated my wood working game. Adds a level of fit, finish and precision that I lacked before, despite hours of planning and wasted effort. Now, less waste and confidence increasing. Great for home workshop. Not festool level, but it is close at a fraction of price. Recently have purchased several WEN items (air filter, saws (plunge and miter etc) and more). They are as good or better than the Ryobi level products but even cheaper. Can outfit my workshop for a fraction of higher priced brands. Starting to trust the brand. Wife asked to borrow, She assumed it would be useful in kitchen to link shortbread cookies for a tiramisu style dessert. (She was joking but her comical attempts were worth the cost of purchase alone). Btw - dessert was a mess but delicious.

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!

A very good value for a hobbyist.
I bought this for an upcoming project. I've been a woodworking hobbyist for 50 years but have never felt a strong enough need for a biscuit joiner until now. After 1 practice cut on a piece of scrap, I tried it out on a a small project (6 biscuits - see pic for context) and found it much easier to use than I had feared. It came set up almost perfect for placing the biscuit in the middle of a 3/4" board, which is what I will need for my big project. I didn't measure how accurate the 90° setting was out of the box, but it was plenty close enough for the biscuits to work perfectly. All that was required was to clamp the pieces securely, and the rest was really quite easy ... the tool cut cleanly and smoothly, and I never felt like there was any danger of a kick-back. I will state, however, that I followed the advice of another reviewer here and bought a CMT blade with it, so I can't speak to the quality of the stock blade. I'm very pleased with my purchase ... I assume it won't be as robust as the models costing $100 more (and up), but I believe it's going to be a very good tool for someone like me who won't need it very often.

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.

Ótimo produto!
Ótimo produto, pena que só dá para usar com um tipo de encaixe (biscoito).

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)

Custo-benefício inigualável.
Custo-benefício inigualável para os brasileiros. Boa construção, com maleta resistente. A única dificuldade é o padrão da tomada, que é o americano e precisa de adaptador no Brasil.
