Rated 4.0 out of 5.0 by larrylee Good Quality, Light Duty chainsaw chain sharpener
This same sharpener is offered as the Blue Max M/N 5655 (now $50 at HD, was $40 when I bought it), the Buffalo Tools M/N ECSS ($40 at HD), and the Chicago Electric M/N 93213 (discontinued, was $40). The only difference appears to be the color of the plastic and the length of the warranty (1 year for Blue Max and 90 days for Buffalo Tools). All share the same poor user manual with incorrect specifications (the correct chain vise capacity is 0.080" to 0.050", not 0.8" to 0.5"). All use the same 4-1/4" diameter by 1/8" thick grinding wheel with a 7/8" arbor (available from Harbor Freight and others). The Blue Max 5655 does seem to be put together with better fit and finish than the old Harbor Freight 93213. I have not tested the Buffalo Tools ECSS but the reviews indicate the same degree of satisfaction as for the Blue Max. Once you get a little practice, it is easy to do a good job sharpening a chainsaw chain. One of the other reviewers suggested watching some of the videos on U-Tube (including for the Oregon professional model) and I strongly agree.
I suggest one small modification. The sharpener is put together with a small metal washer between the plates of the chain vise on each of the two end mounting screws. These washers are about 0.080" thick and when you tighten down the center bolt to hold the chain in place, the plates of the vise are bowed together and bind the chain only near the center of the vise (at least for 0.050" chains, which are the most common). This is not always secure enough to keep the chain from moving when grinding it. I recommend replacing each metal washer with a 3/8" OD, 1/4" ID, 1/16" wall "O" ring (available in the plumbing department as DANCO #5 O-ring, ~$2. for a box of 10). That way the plates of the vise bind for their full length.
There is one other issue with these inexpensive grinders compared to a professional grinder (like an Oregon). There are two angles that matter the most when grinding the teeth on a low-profile chain : one is the angle of the chisel at the top of the tooth relative to perpendicular to the chain. That angle is typically about 30 degrees and is set by adjusting the angle of the chain vise. However, you don't want the front edge of the tooth to be vertical, you want the front edge to have a taper underneath the tooth so that the front edge is sharp and will cut into the wood. On a professional grinder this second angle is also adjustable, but on these inexpensive grinders that angle is fixed at about 27 degrees from vertical. That only matters because the various chain manufacturers recommend different angles for their chains. For their low-profile chains, Stihl recommends 15 degrees for most and 30 degrees for a few. Oregon recommends 35 degrees for most of their low-profile chains. 27 degrees is a reasonable compromise and few people will notice the difference in terms of how the chain cuts. But, as a reviewer for the Buffalo Tools ECSS noticed, the first time that you grind a Stihl chain that is at 15 degrees you have to take off more metal to get the top edge of the tooth sharp.
All in all, these inexpensive chain sharpeners are a good investment unless you are sharpening chains as a business. Then you want a professional model with a diamond wheel.

Easy to use, if you do a lot of wood cutting this is an excellent product to keep your chain sharp. Only takes about 5 minutes to do a chain.

Took just a little while to set up and understand each setting but it was not hard to do. Once everything is set, then sharpening the chain goes quite quickly. Obvious improved cutting performance after sharpening.

Rated 5.0 out of 5.0 by CGlo Godsend, this is truly the best purchase I made in 2014 and years to come.
When this was received it was taken to the building and hooked up immediately, It took us longer to find lights for the area and it went straight to work, So happy that I made this purchase, makes me ask myself daily Why I didn't do this sooner. Don't wait this is the best
