matches my PID'd Silvia

This machine rocks! For crema and intensity of flavors, it is in the same league as my Rancilio Silvia (with PID temp control added). Flavors are a bit smoothed out with the Twist, which makes for a more forgiving espresso if your beans are less than stellar (off notes are muted). Make sure your grinder can grind fine enough and don't forget the preheat.

Near identical match to original unit. Description on item made me cautious, as listed as both 1725 and 1650rpm. Motor tag specs the 1650 as I needed, and amperage draw was correct. Both of these specs vary with your incoming power of course, but was nice they matched factory spec. One stud slightly bent in transport but easily corrected. All leads had spades in place, note, this unit requires a 4mf starting capacitor. Straight forward install. If old fasteners or fan are stubborn to remove, apply heat....

Plugged in as an exact fit in my 2002 Nissan Xterra (same plug and all).  Although I had one that looked almost exactly like this -- which was an upgrade at the time.  Look on the back and see if it says Donnelly.  Very nice product.  After driving around for 30 minutes, it calibrated the temp and direction perfectly.  A++.

Perfect fit, functions well and came with the pin.

As long as it's not a TCI -I'm happy. Will still measure to make sure it's within spec. Had to machine .015" off of a TCI unit to make it fit once, so I pay attention to how these are machined. This one looks to be fine at a glance.

Works good on my machine. Not sure if its because of the basked, but i have with same beans and grinding now less crema as I had with the old basket.

worked a treat for my 1961 Bugeye sprite master cylinder.

The color and shape is correct for my 2009 Murano.

The bottom tray din isn't flush with the top din when you use the supplied plastic clips.

this seems to be the wx191 head, not the 190. This looks to fit, but the string never stops feeding. the mold is slightly different, and the images of the 56Volt tool seem to match what I received.

I ordered this replacement for my Ryobi electric mower. It is a slightly more rare model and the old bump knob was substantially different - but this one fit perfectly and works better than the old one. Sometimes I LOVE the internetz. Back in the day, I am sure my dad had to scour catalogs and call all over the place just to get his mower fixed. I just go to AMAZON!

Purchased this paired with&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Genuine-GM-25826329-Air-Inlet-Grille-Panel-Left/dp/B00GV8X7B4/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Genuine GM 25826329 Air Inlet Grille Panel, Left</a>.  It wasn't the perfect fit I was hoping for from a genuine product, but I'm sure I'm the only one to notice.

Not an exact match for the one taken from my Dell e510.  The connector for the optical (DVD) drive was of the SATA type, not the older 4-pin.  I solved this by cutting off the supplied connector and the appropriate connector from the old PS and splicing the wires.  Works flawlessly in all respects now.

I originally searched Amazon for a WD2500BEVS (NOTICE the S)
So I found one for $76 (or at least I thought it was the right one), I purchased it and after receiving it I knew then I had ordered the wrong one. It's annoying how similar part numbers come up when you search on Amazon, but it was my fault that I did not catch this detail.

The WD2500BEVS is no longer in production, so I was stuck with a broke computer and a new hard drive for a different computer. After looking at the two hard drives I noticed they were still similar. The metal casing off the old S model can be removed and installed on the T model. The way the two models plugged in was also different, the T had pins, but the S had flat connections. This was was changed by removing the plastic clip that contains the connections from the S model and snaps into place on the T model. The plug and housing is now exactly what I needed for it to work in my computer, and my old hard drive looks like the S model I had just purchased.

I am super happy this worked out, because I was facing the fact I would be buying another computer because of a discontinued part.

My driver's side regulator went out so I ordered this unit which happened to be made in Taiwan.  But you couldn't tell the difference between the stock one over the replacement in a side-by-side look.  It installed without issues and worked as advertised.  'Couldn't ask for anything more.

For largely sentimental reasons, I keep my old Powerbook Pismo running. I use it for my ongoing project to digitize all my old vinyl (even though I could probably afford to just replace most all of them via iTunes ...). In any case, every few years the PRAM battery needs a refresh. This one worked fine and installed directly. The connector fit fine and my Pismo is up for another few years. BTW, this one shipped quickly and all that, too.

I purchased a pair of these because one of the bulbs in my 2002 BMW 330ci had cracked and was dimmer / discolored. This product is identical to what I assume are the original bulbs in my car - Philips D2S, made in Germany.

I originally planned to have my mechanic replace the bulbs but when I saw the OEM price from other online retailers for BMW parts, I thought better of it and decided to buy these from Amazon and replace them myself.

I've not yet driven at night to compare brightness, but in daylight they seemed sufficiently bright and I feel great knowing these match exactly what I had previously.

*** UPDATE: I hadn't seen the notice to confirm authenticity of the bulbs, so I checked after installing them. One of the two I ordered did not appear legitimate through Philips' web site. So, thanks to Amazon's gracious return policy, I've returned both (lost track of which came from which box) and will be re-installing them when the replacements arrived.
