Since we see a mixed bag of experiences with WLL here I thought I'd share my own experience.
In May or so it became clear that the pump on my Office Pulser was shot. I used to be a big DIYer on this stuff but with two toddlers, job and extensive volunteer commitments I simply don't have the time anymore. So I initiated service with WLL's service dept. They have a minimum $45 charge to examine the machine which is applied towards any repairs. They emailed me a form to fill out and I shipped it with the info. I also requested to be upgraded to the newer brass screw OPV in addition to the repair. BTW, Fedex Ground was at least $10 cheaper than UPS as usual.
They examined the machine and sure enough I needed a new pump. the total cost was around ~$270 including shipping and that included pump replacement, replace group gasket and shower screen, new OPV and i think a bit of cleaning around the head. Labor charge was $132.
The negatives: shipped in styrofoam peanuts. I have no idea why people use this stuff anymore. To me it is such a pain in the neck for a box this size. Communication is not WLL's strong point and I can bet that this has probably led to a lot of the problems that we've read about. There were no notes on what it had been calibrated to or if it had been calibrated at all. I wasn't quite happy with the pressurestat setting and in the end I had to calibrate using my senses. I have no idea what the OPV setting is. Also they had to resend several emails after I did not receive them. This was clearly a problem on their end as it happened with two different email addresses and t was not going to spam. It would also be nice if they had auto notifications at various steps in the process.
In the end it took about two weeks from door-to-door if I recall correctly and the work was good as far as I can see but I think they could take some fairly minor steps that would result in happier customers. Let me know if you have questions.
